Hi Dmitry,
I don't know.  It would be better to try just deleting the TER card only (since the message says that is the thing to do), and then you would not need to add the MYR back later.
Best,

After finishing refinement in ChimeraX/ISOLDE, I loaded the model and the map on https://validate-rcsb-1.wwpdb.org/. But this website showed me the error:
