Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

GPT PMBR size mismatch (134217727 != 268435455) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
