Header Menu not working in elementor

Hi – My website is a wordpress Insprio theme with elementor for editing. Everything on my site works except for the menu on the top which does not respond to the theme customizer – it looks fine in the customizer – but reverts back a huge font when I leave customizer. The problem plug-in is Elementor because the header looks fine once I turn off all the plug-ins – but the rest of my site is barren without the elementor plug-in. Please help!
