In that case I presume no SD card has been installed. If one were present, I think information would be shown just below the info on internal memory.
I suppose it’s just possible that the “Phone” app has lost permissions to make and receive calls for some reason, though in both the versions of Android I have available to check on, neither will allow the permission to be withdrawn, understandably. It’s something that might be investigated if other possibilities fail to get results.
You might read through some of the posts of other people with call problems. And here is one from another FP2 user after upgrading to the same build number that you are using.
