## Description

### Steps to reproduce

1.  Login to QA Edge
2.  Go to a work packages list
3.  Click on "Filter"
4.  Try to trigger any kind of error, for example: select a custom field + is (operator) + choose the same value twice in the dropdown
5.  When you get _"Your view is erroneous and could not be processed. X filter has invalid values.",_ close the pop-up and try selecting any other filter for any other purpose

### What is the buggy behavior?

*   There is another error message: _Your view is erroneous and could not be processed. Highlighted attributes Attribute(s) not highlightable: Null, Null, Null_
*   This error message always appears after another error message, which is wrong. Apart from that, the page becomes unusable and even if we close it, it keeps appearing all the time and preventing the user from filtering further. Even if all the filters are removed, work packages are not shown.

### What is the expected behavior?

1.  There should be no error messages once we close the first error message.
2.  Filtering should work after we close the error messages and remove the filters.

### Important note

We have another bug ticket for dropdowns displaying already selected values.
