Propeller change

[Zandor hercules]

Trying to change propeller fifishv6. Seems like there is a spring or something preventing easy removal. This is after removing the blade cap. Please tell me what I'm missing.

I wish I can pull it away .5cm then it snaps back....like I'm pulling the entire motor assembly or glued...??? I've watched the videos...looks simple. I'm afraid to force it off.
I appreciate all the help. Thx
