ACF doesn’t work with Search & Filter anymore?

Hi,

I created a couple of ACF fields that required for another plugins Search & Filter. I did this before and S&F can find the ACF automatically from the drop down. However, I am not able to see these ACF fields anymore from S&F post meta. I can still see the old ones I created before but not the new ones.

Wonder if anything else I need to configure to make it work? Thanks!
