Root motion rotates with half strength if using layer per bone blend

I implemented turn in place using montages and root motion. For some reason it works with half strength if I blend turning montage, but not every time.

Setup:

How do I fix it?

For example, root motion rotates fully when I blend it with Pistol Aim, but only half with Rifle Aim from the same animpack.

Still stuck

So it’s happening when you apply montage on the pose with root motion enabled. Is there a way to switch off pose root motion and have full montage root motion strength?
