There a bug affecting the filter un Drawings. It looks like the last filter entry is stuck in the box... CRP filter box in Drawings does take any changes and stay stuck with last saved criteria. This only affects Drawings but not Vizualisation.

I have to admit I struggle to clearly identify the bug as before the bug appeared, I found the filter feature a bit awkward and I did not like the way filter validation worked or at least the way I found to make it work. I never knew "tab" to exit would validate the filter. After typing in the new value, I would reselect the filter type in the dropbox menu... not practical but it clearly worked before the bug. I think the filter value should be validated by either typing "enter" or click on a validation button, any other way is not intuitive in my opinion (tab or click anywhere). Concerning saving filter value after it has been validated, I think the value should be saved for each filter type and not one value for all filter type. This would allow to quickly swap between two filters without typing again and again the values. This can be very useful when you have a huge amount of splays and want to see something that one filter cannot clearly segregate. Maybe you could even develop a secondary filter, to increase the filtering capacity and segregates splays. What do you think?
