Help: EBMM Majesty: stiff bridge when reverse dive bombing

I have a EBMM Majesty in C standard, 10 high E gauge.

Today changed the strings and I noticed that it feels like the bridge is blocked when I try to do a reverse dive bomb. This problem didn’t exist before changing the strings.

When changing the strings I removed all of them to condition the fretboard, I used a piece of cardboard to block the bridge. The bridge was level after tuning to pitch, I haven’t changed the tension of the trem springs so it is exactly like before changing the strings.

I uploaded a video here describing the problem: Imgur: The magic of the Internet

Normal dive bomb is ok

Reverse dive bomb with forward trem arm doesn’t go all the way but is feels blocked.

Reverse dive bomb with backward trem arm goes all the way, seems OK.

I appreciate all help I could get!
