Custom taxonomy doesn’t list items

Hello

I have created a custom taxonomy for the Post type. It’s the only one available for this type.

I add some items in this taxonomy.

Then, in a Post or an Article, I add a Post Gridd block, I can filter by post_type, I choose “Post”, my custom taxonomy is listed, but the filter for selecting an item is not showned.

If I created a second custom taxonomy for the Post type, I can choose in the filter between the first taxonomy or the second one. But no filter on the items.
I have to choose the second one taxonomy to make available the filter, and then select the first taxonomy to finaly have the filter on the items I wanted.

Seems like a javascript event not fired at first when selecting the post type.

Thanks for your help
Hope that’s clear enought.
