Issues with "FX/Options/Chain PDC mode" (FIXED)

[zabukowski]

Steps to reproduce issue 1:

1. change "Chain PDC mode" option (track's FX window menu) to any value ("Ignore plug-in delay" for example).
2. undo -> it goes back to default (Per-chain compensation), which is OK
3. redo -> nothing happens !!!

Issue 2:

Sometimes "Chain PDC mode" resets without any obvious reason. At the moment i don't have steps to reproduce, it's happening very randomly (track1->send->track2->send->track3). Tracks have pretty high latency, that's why i am using "Ignore plug-in delay" option, otherwise project doesn't play at all (known issue with high-latency plugins, folders etc.). I suspect this issue happens when changing automation (items?), but as i said, can't replicate it. Will try further ...
