I had a locked map (lowest zoom) & placed a map into an item frame within the map's range. A green marker was added to the locked version of the map. I removed the previously placed map & item frame but the green map marker persists. I tried placing other solid blocks in the space where the item frame had been but it did not help.
Screenshots include the viscinity of the map & the specific blocks where the item frame was placed.
Thank you for your report!
