It seems FBPM has replaced FBFT at some point, unless the second location indicator is still used for the military part of the airport (can’t check this as the AIP is not public). The records for the latter are tailored, untouched since 2012 and no charts are available.

Possible duplicate airports (Botswana)

Thank you.
It seems it has indeed changed after further examination:
