[Edge Gateway 5000] "Key Storage" option repeated twice in BIOS 'Security → TPM 2.0 Security'

As outlined in the title of this thread: I have a few Dell Edge Gateway 5000 that have the "Key Storage" BIOS option repeated twice in the "TPM 2.0 Security" settings, ranging from UEFI BIOS version 1.11.02 up to the most recent 1.30.00 at least (mines arrived with version 1.11.02 from factory, have not tried earlier firmware releases).

May I ask for one of these options being removed in a future UEFI BIOS release?

Thanks in advance for any help.
