Double logo on Mobile with Astra theme

Astra agency and Max Mega Menu Pro are not working so well together at the moment. I have an issue with the mobile site. I have to add the logo in the megamenu mobile menu toggle bar designer in order to see the logo in my menubar. At the same time it is showing the Astra logo big above my menubar (on mobile). The logo is added in the customiser and works well on the desktop and tablet.
Also, in my sticky header the logo is not showing at all.
Last one, the menu bar is not full width, already contacted Megamenu before but it is not completely full width yet.
Thanks for your help.
