Sorry i cannot tell why your fdisk runs sometimes report bad backup
tables and sometimes don't.
Especially riddling is this from an earlier post of you:
Disk /dev/sda: 2.73 TiB, 3000592982016 bytes, 5860533168 sectors
...
Device Start End Sectors Size Type
/dev/sda1 2048 5860532223 5860530176 2.7T Linux filesystem
GPT PMBR size mismatch (234441647 != 468862127) will be corrected by
write.
The backup GPT table is corrupt, but the primary appears OK, so that
will be
used.
The backup GPT table is not on the end of the device.

Have a nice day :)

As last posting I think these GPT error messages are about the disk
listed below the error messages.
