GameplayTag category filters do not function on BP SET nodes.

BP SET nodes for FGameplayTags do not respect category filters, instead the dropdown shows an unfiltered list of all gameplay tags.

Given the MyValue property decorated as follows:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=MyCategory, meta=(Categories="MyCategory"))
FGameplayTag MyValue;

Expected:
Blueprint SET node for MyValue would contain a dropdown list that is limited to tags that match the filter (MyCategory).

Actual:
Blueprint SET node for MyValue has all gameplay tags in the dropdown list regardless of category.

create a C++ actor class with property MyTag of type FGameplayTag

decorate the UPROPERTY with meta Categories with any filter string

build and launch the editor

create a root GamePlay tag with you filter string and some child tags

create some other GamePlay tags that are not under the matching tag

create a blueprint from the new actor class

notice you can edit the default value of MyTag and the UI restricts you to matcing tags (filters working correctly)

drag the variable onto the blueprint and create a SET node

click the tag drop down in the SET node and notice it shows all gameplay tags unfiltered (filters not working correctly)
