This list has a number of enemies which I don't think are correct - the list covers armies that were really only used in Iraq, bits of Syria and (very occasionally) Egypt.
Arab Indian - any conflict here would be with armies from the Khurasanian Dynasties list which has it as an enemy..
North African Dynasties, Christian Nubian, Beja, Abyssinian - the caliphal army did not operate in Egypt and Africa other than some conflict with the Tulunid/Ikhshidid regimes. It is possible that regional forces did do some fighting though.
Khazar - fighting in the period covered by the caliphal list was quite low level so it'd just be the regional forces I think.
This will be corrected in the 2021.01 version.
