The issue most likely is that you have enabled the ‘Blog’ menu item to be a mega menu hence the empty white box. Disable that option for the ‘Blog’ menu item.
@safiweb thanks for this info. I see that there are options to select under the mega menu section in each Post Category menu item, but I don’t see an option to disable the mega menu item. See image below to see what I am seeing.

Are you able to provide more info on how to disable that for the Blog menu items?
Thank you for the support.
@safiweb I just figured it out! Thank you for pointing that out to me. Really appreciate it.
Btw the menu items appear on the big box but are invisible because, there are white in color. See… https://paste.pics/0ec3f0f1f47e47ba2b03da64bcab6be7
Check the option under the parent menu item ‘Blog’.
