Logo not appearing

Hi,

I’m currently using the Astra theme on my website and I really need help to get my logo appearing on my menu.

So far I’ve tried what was recommended; deactivating plugins, adding the logo to the transparent header and clearing cache but the minute I closed the customizing panel, the logo will disappear. Somehow the menu items remain. I’ve also added a button to my menu and that also does not show up. Right now, I added an image of my logo on the top left of my page giving an appearance of a logo but this is a temporary fix and I hope I get to solve the situation as soon as possible.
