Claymore config parsing affected by AMD OC settings

Issue happening for one of the rigs that uses shared wallet.

When i put such settings (same if i put CoreClockes):

i always see this (after reboot, hot apply works):

And everythig is fine when i use only DPM for each GPU everything goes as it should.

Please clarify, i doing something wrong (tried with different sets of setups - includeing values for each specific GPU)?
One minor comment - this issue appear for 12gpu rigs. For 7 GPU rig seems to be fine
