Plugin conflict with Gridbuilder WP

I love Ivory Search and use it on many of my projects. I’ve just embarked on using Gridbuilder to enable faceted filtering/search (as an alternative to FacetWP).

Everything seems to work fine except for the Results Facet that displays the number of results after various filter selectors are checked.

If I deactivate Ivory Search it works correctly.

Any suggestions on how to resolve this conflict?
