Problem with creating SubClips when proxy media is generated

I can't normally create and play more than one SubClip from one original clip if it has generated proxy media and option "Use proxy media if available" is activated. Tried on DaVinci Resolve 17 Beta 4 and Beta 5.

My steps:
1. Import clip into DVR17
2. Generate proxy media: right click on Clip - Generate proxy media
3. Activate option "Use proxy media if Available": Menu Playback - Use Proxy Media is Available
4. Create three SubClips from the same Clip by marking in-out marks and Option+B.
5. When I play new created SubClips they are all completely the same although they made from different parts of original Clip. All SubClips are the same as the first created SubClip.
6. When I deactivate option “Use Proxy Media is available” I can normally play and use all my SubClips.

Could anybody help me to solve this problem?
Thanks!

Tried on Davinci Resolve 17 beta 6 on Windows 10. All the same(((

Found this issue myself, it's very confusing and find out after creating 10+ subcilps with wrong timing than selection. And there is no way to create subclip with selected regions when proxy enable.
Disabling proxy will move subclip region to selected ones.

This showing that proxy feature can not be used because of this blocking issue.
Please fix this ASAP

DaVinci Resolve 17 Beta 6 / Win10

The problem with subclips generated from clips with proxy media is still present in DaVinci Resolve 17 Beta 8. I created a subclip to a clip with generated proxy media and the subclip will always play the proxy media from the start of the original clip.

In Resolve 17 Beta version 10, the error is unfortunately still present ...

Can confirm, this error still present in 17.1 Build 24. Seriously, this needs to be fixed!
