Strange behavior inOffline editor

I apply 3db of gain to 2words, it works fine, then I decide to add 2 more, it does nothing, I try 4db, it applies 2more, not 4 more,.Then I decide to apply 4db to the whole phrase (7 words), so I highlight the whole phrase, after hitting apply, it does nothing, and the highlight goes back to the first 2 word phrase. I use this a lot. Wierd :astonished:

Sorry, this is after 10.20 update
