Hi @CenkDemiroglu - Thanks for sharing the app. I can reproduce the issue you mentioned, but it seems that neither of these are regressions.
1. The issues with table filtering
Since the filter widget is placed inside the Map widget container, it got reset when you switch the section views - that is why you cannot see Table filtering behavior in another view. You can see that the filter criteria have been reset once you switch back, as well.
This is a long-lasting behavior (checked a few release versions ago, same behavior), and we will help take a look at it. Meanwhile, the workaround is to change the layout a bit and move the filter widget out of the map container, then it will work properly.
2. From my test, the first filter is not correctly filtering features (even though it removes all features, it shouldn't) - which would be caused by a rendering mechanism which we will contact the corresponding team to take a look at. The second one is working properly.
