Upgrades not working or not cumulatives?

A quick question todevs about the way upgrades works :
Are they cumulative or bugged?
It is obvious for range upgrades but often you dont have the right range for weapons :
For example : a chaos flagship with the +4.5k range upgrade and using lock on will only have a +4.5k range.
Same for aeldari with targetting node stance + upgrade and the +4.5k range flagship upgrade (and many other exemples).

Yeah, they mentioned this in the Community update, apparently it is bugged in this beta.
