Hey @sean1! I see what is happening and I am afraid we cannot achieve this with CMS Filter and CMS Slider. The issue is that CMS Slider will pull the entire list without the filters applied.
I’ve tried applying the CMS Element setup for the finished slier but the filter doesn’t work after this. This setup will be natively supported for Attributes V2, which is still in the process of being finished.
If you can wait until release I’d advise we wait and set it up then. At the moment we can try Webflow’s native filter shown below
This should result in only the “Speaking” items shown on the slider.
On another note, I noticed there are 2 CMS Slider scripts on the page! You might want to take a look at your site settings and remove the extra script from there!
