Boon Removal on Training Golem

[Squidgeididdly.2930]

I've noticed that Alacrity I generate while attacking the raid training Golem is vanishing quicker than the boon should.

I did see another thread on this, but I'm not sure if it's the same bug. 

 

Maybe it's related to the bug mentioned on this page?

"(Note: there is a bug with Regeneration at the Golem: It will apply level 1 Regeneration, granting you insufficient Boon Duration. You can fix this by using "Reapply stored configuration" at the console)."
