Can't change position of a navbar

Hi everyone,
I’m working on that small one-page project that I wanted to complete with a last section containing a small navigation bar, however, anything I’ve tried didn’t work and the navbar (the Réservation/Contact bar) seems to be stuck at the bottom of the first section although I tried to put it bottom of the second or top of the third (empty) one.

Anyone has an idea, what did I miss ? I’m still kinda new on webflow, mistake probably is on me.

Thanks by advance
