Bought Isotop Addon. Default filter no working

Hi,

I purchased the “Isotop Addon” because i really needed the default filter feature for my website. Turns out, after I installed the addon, everything is OK, except for the Default filter that doesn’t work. When i try and generate the shortcode, the dropdown menu for the default filter has no options available, only says “- No Default Filter -“. I created the filters but they don’t seem to load on there.

Would really appreciate some help on this
