Summary Orders/Invoicing Report: output table misaligned

Hello,we are analysing ProjeQtor as a replacement for our old project managing system
It's important for us to understand the way to monitor the process quotation->order->invoice and the matching wih activities on projects
Making some tests on orders/invoice coverage, we have found what seems a bug; here the description.

When generating the Summary Orders/Invoicing Report (Reports->Financial->Summary of orders / client invoicing), the generated table ha misalignements in cols/rows.
In the case depicted by the attached image:
- Project has two orders: ORD0242000140, ORD0242000130, with budget 5000 and 2000 respectively
- two invoces have been charged to the order in the first row (ORD0242000140): 2021/003 and 2021/030, with amount 850 and 2830 respectively
- no invoce charged to the order in the second row (ORD0242000130)
- up to column "Invoice" the table is right
- then the date of the second invoice is displaced under "Invoice amount"
- the rest of the table to the right is a mess

Context:=> version of ProjeQtOr:  9.4.1=> browser used (en version): both Firefox 96.0.1 and MS Edge 97.0.1072.69=> nothing noticeable in log file
