Piano loop addictive drums issue

[ProfRekT]

Hi

Dragging a loop from addictive drums to into piano roll is fine but dragging another drum loop only replaces the first.

I believe this is an issue BUT why?

Same happens with Ample Guitar, why?

If this is an issue why has it not been addressed, I can drag multiple loops directly into Reaper.

I can’t even drag drum loops directly into the song line with FL studio
