Navigation on Mobile bug

Hi everyone,

Not new in Webflow but trying to push my boundaries for this new website I am doing.

Custom-designed the Navigation bar and trying to make it show on Mobile and it seems to show an empty bar. It seems to not show at all on Android.
I did try SHOW/HIDE option but still did not work.



Could anyone help?
