Can not create new filters

[StigBrenden]

Hi,

I have a big problem creating new filters in my project.

When I'm trying to creating a new filter or duplicate an old one, something strange happens. 

The underlined text is my new filter, when this was created I can no longer select the other filters in my list or edit my new filter.

Has any one seen this problem before?

the filter may be corrupt...can you delete it and recreate it?

purge command does not purge filters (fyi)

Hi Thanks for the proposal, but this happens anyway.
When I try to create a new or duplicate filter, it appears in the list, but when I try to select it, it is not selected. It is also not possible to choose any of the other filters either. All i can do is choose cancel. Having worked with Revit for almost 6 years, this is the first time I've experienced this.

If it lets you delete a filter do that, I ran into the same issue.  I wasn't able to create new filters or edit the existing ones but as soon as I deleted 1 rule-based filter it let me create a new one.  Not sure if its a glitch in Revit but it worked.
