V 5.0.1 - I can't see a list of items in "Detail of list element" Pop-up

I have an empty field (ex.: customer).

I click on "Search/View item" button.

I see "preparing view", but no list are displayed.

So, I see the number of items to "1" in the header window (see : attachment).

I add a second customer and I have the same issue.

I test it with Firefox and Chrome.

I flushed the cache and I use admin user.

No error in the log. Just this trace.
