"Copy sampler audio data" is grayed out and can't be unchecked
Hello
I recently found out that my MainStage concerts suddenly have huge file sizes.
The reason is, that "Copy sampler audio data" is checked but grayed out and can't be unchecked. The same applies to Space designer IRs and Apple Sound Library content.
Did anyone have this issue as well and can in be resolved?
The MainStage version is 3.6.2
Thank you
