partial access to Teams & Pools; unable to attach new Resource to Organization

Since the 8.2.0 update I have the following strange behaviors on permissions :
- under an Administrator profile, I can view all Pools & Teams in the list, but I can't access any in the details view ("You don't have permission to access this element ..."
- we can't attach an Organization to a new Resource at the creation step, though we can do it by editing the Resource after its creation. This is obviously a problem when access to Resources by some profiles is to be restricted to "same Organization"...

Note: there also is a - probably unrelated - bug on access rights but I mention it just in case it could signal you some common cause from the database : in Access to non-project-dependent data > Legal Mentions I have an "8" for Administrator's access that I am unable to modify (update & read are proposed in the dropdown list but neither choice is taken into account when saving the page).

I attach the log of the day when the application was updated to 8.2.0. *
(Today's log is 45Mo, i can't decently attach it but if you point me to something, I can search inside).

1st issue : as admin, re-enabling the "Leave" module (which I had disabled when in 8.1.6) got the lacking 'Env parameters' screen available again. After updating to 8.2.1 as advised, I enabled a Resource as Employee then defined a valid module administrator, then disabled the module. The Env pram screens remain OK until now.

2nd issue : we still can't select an Organization at Resource creation. It seems like your demo instance undergoes the same issue (unless this behavior be a 'feature' I haven't yet seen the use of
As a consequence I must give access to the whole table of Resources to some people able then to attach them once created, which is quite cumbersome and error-prone.

3rd issue : In fact the "Generic functions" section in "Access to non-project-dépendent data" can't be updated and still displays "8" for Admin profile on Legal mention data. I suspect this new "legal mentions" thing to impair the whole section.

Thanks for the last 2 issues recorded.

For the first issue, the steps I related are the workaround, not the way to reproduce. I don't get the steps to reproduce : I just got the issue again, without any admin action, nor system update AFAIK, on Friday evening everything was OK and today I noticed that every "Env param" below "Resources" had disappeared, as have the associated lines in "Screen access" configuration.
Once again, I had to enable the HR module, enable my admin user account (which gets selected by default in Global params as HR habilitations admin) as an Employee resource, by which I recovered the missing lines in "Screen access" and was finally able to re-enable those Screens (Pools, Customers, etc.).

I don't see anything useful in today's logs though. In Friday's logs I don't find anything visibly related, but I see a (maybe unrelated) recurring error (cf. attached logfile extract).
