Somes troubles with Resolve 12.5 Beta

Hi everyone,
I experienced some problems with Resolve 12.5b and Resolve Studio 12.5b :

• If I select all the content on my timeline after the playhead (Alt+Y), the software freezed many time. (My timeline was 10 minutes long)

• If I add a DURATION on a marker, I don't see the duration indicator on the timeline (like a 5 secondes marker trail).

• Sometime, I can't draw a audio keyframe. I can add one on the next or previous frame but not on my specific frame.

• Sometime, if I adjust the audio level, the waveform updating at the wrong place.

• PASTE ATTRIBUTES option don't include the LENS CORRECTIONS attributes.

• If I add a audio transition between 2 clips and I move it with the trim mode (+10 frames for example), I hear my old audio transition sound in the new mix. I need to delete the transition for resetting all and add it again at the new position.

• If I have a left or right aligned text, the TEXT TOOL change the characters as a centered-aligned. It's not practical with graphics templates.

WHIS LIST :

• A REMOVE ATTRIBUTES option to reset many clips.

Thanks a lot if you have answers!
