BLF (busy lamp field) LED is on when extension status is idl

I have a multi hosted PBX running Thirdlane PBX Manager on Asterisk For one of my tenants, all of the users have a Snom 320 with all phone extensions programmed as a BLF. All phones have two extensions BLF (busy lamp field) LED on for extension 1100 and 1101 whether the extension status is idle or in use. In the past I have removed both extensions and auto provisioning and re-added from the PBX to correct the problem. Is there another way for correct this issue?
