In Zetta 4.19.2.370 and 4.19.2.374, Zetta will crash when filter any column twice in library. You can easily recreate this issue under follow steps:

1.Open Zetta library module, dock this module, then click save layout.

2.Close Zetta and reopen, filter any column, then remove this filter, you will see the value showing on this column will disappear, filter this column again, remove this filter again, Zetta will crash.

I don’t see this issue in Zetta 4.19.2.290. And in Zetta 5.20.1.764, Zetta will not crash under above steps, but the value showing on the column will disappear after filtering any column and removing this filter.
