websupporter on "[Plugin: Filter Custom Fields & Taxonomies Light] Columns not working"

I'm posting here from the reviews cause it could help others in the future.

The filters are stacked on top of each other without me putting anything in the Custom CSS box.

Also, nothing happened when i keyed it into the CSS box.

The search results layout are also wrong. 1 column seems fine, but for 2 column, all the results are on the left and nothing on the right. Same goes for 3 column and 4 column layout; the column on the extreme right is empty.

Re-installed the plugin and nothing changed.
What should i check in the styles.css?

Sorry for all the trouble! Really loved the plugin but all the issues pop up when i'm adding new filters... I will definitely buy it if my current issues are resolved
