Cannot update Member Status in Membership 2 Pro 1.1.1

When attempting to change the status of a member in WP Admin -> Membership 2 -> Add Member -> Manage Subscriptions, any changes set to the status are not applied to selected member. This is confirmed by going to WP Admin -> Membership 2 -> All Members and checking their status there after the attempted change.

Plugin conflict test performed. No debug.log output. No JS Console output generated.
