12.3HD HEAT Pre/Post Bug?



Hi guys, I just wanted to ask you if anyone can confirm this behavior or if it´s me who is missing something?

In the HEAT manual it reads -HEAT processing is Pre Inserts when the PRE button is lit. Pre is enabled by default-
BUT if I open a new session/existing session without HEAT enabled and I go to enable HEAT it appears on every
channel WITHOUT the Pre button lit. Therefor I would assume it´s in Post mode then, right? There ain´t no bypass
activated or any other setting applied, it´s just HEAT opening as default.
According to the manual it should be in Pre mode by default.
So is this a bug, wrong information in the manual or am I missing something?

Thanks in advance.
