Rules integration not working

I see the values to use this in rules, and my system tells me it's updating the expiration date, but nothing actually happens to the expiration date field - the box is left unchecked and hence there is no date assigned. It does not appear to be saving the data.

Here is my rule (I tried both "+365 days" as well as "+1 year"

{ "rules_set_expiration_date" : {
"LABEL" : "Set expiration date",
"PLUGIN" : "reaction rule",
"REQUIRES" : [ "rules", "user_expire" ],
"ON" : [ "user_insert", "user_update" ],
"IF" : [
{ "user_has_role" : { "account" : [ "account" ], "roles" : { "value" : { "4" : "4" } } } }
],
"DO" : [
{ "user_expire" : { "account" : [ "account" ], "expiration" : "+365 days" } }
]
}
}

============
Here is the rules debug log:

=====================

I feel like there should be something turning the user expire option "on" first, THEN this would run:
{ "user_expire" : { "account" : [ "account" ], "expiration" : "+365 days" } }
but I know so little about coding that I won't attempt a guess beyond that.

If there is any insight, please let me know. My user accounts do not appear to be changing at all. Much appreciated!
