Are Updates Allowed? rule not working

[1minManager]

I’m using the following as an Are Updates Allowed? rule:

IF(
	OR(
		IN("Manager",INDEX(CURRENT_User[Type],1)),
		IN("Admin",INDEX(CURRENT_User[Type],1))
	),"ADDS_AND_UPDATES",
IF(
	ISBLANK(UserEmail()),"ALL_CHANGES",
	"READ_ONLY"
))

but when I try to edit a record I get:

Table 'Plot' does not allow this operation. Expression result: 
'READ_ONLY'. 
Expression Trace: 
{"key": "IF(OR(IN(\"Manager\",INDEX(CURRENT_User[Type],1)), IN(\"Admin\",INDEX(CURRENT_User[Type],1))),\"ADDS_AND_UPDATES\",IF(ISBLANK(USEREMAIL()),\"ALL_CHANGES\",\"READ_ONLY\"))","result": "READ_ONLY","values": []}

CURRENT_User is simply a slice to not have to use ANY(Select(… multiple times

I’ve tested the formula in UserSettings and as a whole I get a result of “ADDS_AND_UPDATES” and INDEX(CURRENT_User[Type],1)) gives me “Admin”.

So I’m a bit stuck as to how its clearly getting “READ_ONLY” at the table level
