Broadcast ignores taxonomy blacklist

Hello,

we have an issue with broadcast-premium 48.07 (current version 48.14 cannot be used, because every post which is broadcasted stays in an endless sync loop).

If we add a custom taxonomy (tax1) to the blacklist and would like to prevent all the syncing with tax1 * * in the blacklist field, it is ignored.

Every change to the taxonomy is broadcasted, when a post is saved.
We also tried tax1 * term_name or tax1 * name to prevent syncing the name of the taxonomy.

Nothing works. Are there any suggestions what we could try?

We use WordPress 6.1.1.

Thank you
