I set up a Club filter and tested with Checkbox set, Radio and Select box. 

Trying to use these filters in a Pages block fails. Making a selection in the block settings:

After saving:

I checked the database. The filter value is actually saved, but the ACP interface can’t read it properly and the front-end also doesn’t show the block with the selected filters applied. 

I also checked with two filters filter fields. Then it breaks down entirely and what is selected and not selected after saving feels almost random.  

I don’t have a live installation to test this on my server, but you can probably easily replicate this on 4.7.15. I could easily replicate it on multiple installations.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
