[chirp_users] will not copy channel names to radio

[C.S. Arthur]

at the risk of asking a question that may have been posted earlier (several hours of searching failed to yield results): recently purchased a BF-F9 V2+. the most recent CHIRP daily allows me to program all fields successfully, but the channel name field will not copy to the radio.  turning everything off and copying FROM the radio into a new download file shows the channel names are in there somewhere, but they do  not show up on the radio display.  Any ideas?

Thanx
