Amendment of FacetWP workings

I need help with a WordPress project. I have built a filtering system which mostly works as intended but needs a bit of finishing off.
1) There is a filter box which shows what filters are applied. I need this to ONLY show when filters are applied, and not show when there aren't any filters applied. Currently it shows all the time. I have tried an IF statement but it doesn't work as the templating system is twig and the IF statement would depend on the java of the facetwp plugin - and I can't find a way to bridge those languages.
2) I need help breaking down the facetwp shortcode '[facetwp selections="true"]' - basically I have 3 columns showing which filters are applied, and I need the correct filters to show in the correct column but [facetwp selections="true"] just outputs them all.

There are other issues to solve but these are the main two.
