How to effectively report a bug in Logic Pro
Please report bugs via the feedback form as the Logic Devs/Apple do not usually read posts in the community forum.

Even better is to sign up for a free developer's account and submit a bug report via the Dev Bug report system... You can then follow any responses made to your report via that system....
