Too much white space between fixed position button and the footer when scrolling

Hello,

I’m at the stage of prototyping an app, but having problems with the fixed position element (request a quote button) when scrolling. It is fixing to the bottom of the screens fine when scrolling; however, I’m not understanding why there is white space between the ‘request a quote’ button and the “above” element (the footer) on a couple of the screens. Please see what I mean below:

If you play the expertise screen and scroll down, the ‘request a quote’ button sits flush with the footer above it. However, I
can’t figure out how to do the same on the ‘projects’ screen. All content (on both screens) bar the sticky top nav bar and status bar are in a frame.

Please help!

Thanks,

Caroline

I guess you figured it out, both look the same to me?

I did work it out- thanks!
