I will check if any error you mentioned can be recovered.
If don’t I will let you know and you will have to make appointments with the tech team as that is not the correct behavior .
If the full Field can’t see markers it means the calibration is not correct for your Full Field and that is only the reason behind it .
Or in worse scenario technical hardware issue but for that the tech team need to check it themselves.
I will let you know by tomorrow morning .
