Call Queue Member Status gets Auto Enabled

I have a user who is part of a call queue. Her “Accept queue calls” option automatically gets ticked on, on a regular basis. Before it used to happen occasionally but now it appears to be happening more often and throughout the day. Staff rotate on the call queue every day. Her status automatically gets enabled, and she would need to login and have to manually disable the Accept queue calls option regularly. Has anyone experienced something similar / found a solution?
