categories param not working with shortcode in text Widget

Hi,

I am using the [bgmp-map] shortcode to display a map from a text widget.
When using one or multiple categories as parameter, all categories are shown on the map instead of the ones mentioned.

i am using this code

[bgmp-map size="default" categories="duurzaam-ondernemen"]
