I try to explain this as clear as possible, so I hope it will be clear what I mean with this bug.

When you filter on a cast name, and you type in part of the name, you get al the people who correspond to the part you typed in. When you find the person you are looking for and tick the box left of the name, your collection will be filtered by that name.
If you want to filter by another name, you will have to remove the tick in the box and after that, you type in the new name you want to search for.

Now here's the bug:
If you forget to remove the tick in the box of the first filtered name, search for the new name, and tick the box for the second name, you will get all the films both people have worked for. So far so good. This is expected. But when you push the button "clear all filters" the input field where you type in the name you want to filter, will lockup. You won't be able to put in any name there until you close the program and open it again.

Could someone please check if my description is right and clear?

Yes - performs thesame way for me also

Same field, same bug or different bug?:

If you first filter a name, remove the tick after that and then press on clear all filters, the input field blocks.
