Blog category drop down menu near the header in mobile view appears near the bottom footer

I’m having trouble with the blog category drop down menu on the mobile view, which is placed near the header. When I click on the arrow, there is a flash, and I am redirected to the bottom of the screen, and then the drop down is found midway between my blog post area and the footer area (as seen in IMG-1).

However, when I click on the same menu arrow within a blog post, it shows up at the bottom of the screen, which atleast is okay (IMG-2). I’d like to change its appearance to have larger font size, though.

I’m working in Wix Studio Editor.

**I would basically like for the drop down menu to show up right near the arrow and not far from it, and increase the font size, and change the menu’s background colour from white to something else.

I’m also seeing the blog category drop-down appear at the bottom in mobile view. It seems like a layout bug that needs fixing. Has anyone found a workaround for this issue? I’d appreciate any tips or solutions. Thanks for the help!
