When I add a radio station's common "call letters" to the playlist from my "favorites" list or from the "internet radio" list, in a short period of time, the common names either totally disappear (totally blank) from the playlist or else the common radio call letters (eg,WABC;WGN;KABC, etc)  are replaced by a long list of letters and numbers that mean nothing to me.... URLs, I presume. This, of course, makes it impossible to identify which stations are being selected from the playlist ( by scrolling down from "now playing". When I do select one of the blans or the unidentiable numbers , sometime the common name actually does reappear....but it is a guessing game to select what I am actually looking for. (The "favorites" listings are stable and good.) This is a new problem and was not like this in the previous version 7.3. 
I am usine 7.4.1 Build. Can this be fixed and are the devs who are working on fixes know that this is a problem? Any suggestions? Anyone else have this problem? I would REALLY appreciate the fix. This occurs with the Boom and the SB3. The Radio does not seem to have a playlist listing to my knowledge.I am using a wireless connection which ranges from 70%-100% strength. Thank you very much. ( I love the Squeezebox System...this is annoying for me though)
