CHIRP

My uv-2501 will not switch between VFO/M modes. I contacted BTECH and they referred me to Chirp support. Let me preface this by saying I don't believe this is a CHIRP problem because the radio was functioning properly, then starting displaying this issue. CHIRP was not used between the time it was working properly and then stopped switching between VFO/M modes. I was trying program some new frequencies into the radio and could not get it to switch into VFO mode it would just chirp instead of the normal beep when the VFO/M button was pressed. I finally just performed a reset all from the menu. It then went to VFO mode and it would communicate with CHIRP. I downloaded from the radio copied my station list into the template and uploaded. Now it was stuck in VFO and would not switch to memory mode. I contacted BTECH and they said the VFO/M mode was locked in CHIRP settings. First of all, I didn't even know that was an option and I certainly didn't set it that way. I download from the radio again and go to settings there is nothing in the settings menu, blank! I have included the debug list. Is this a CHIRP issue or a radio issue? The warranty is up on June 14, I would like to have an idea where the problem is before then. Thank you, for looking into this matter.
