[chirp_users] Channel program problem

I've a Baofeng UV-5RA and when importing local repeaters in Chirp (only been using since 1/11 & VIP before then & same problem), in Channel Mode it will not ping one of 4 local repeaters but if I set it in VFO Mode, no problems. In Channel Mode, I can hear other local repeaters but one I've programmed; RX Freq.=147.180 TX Freq.=147.780 Tone=151.4 Offset=00.600

FYI, I've 2 other Ts, a Yaseau FT-11 & a B-K LPH-5142 of which both can get the repeater, I can't talk to either of these from my Baofeng While in Channel Mode but can in VFO Mode. Any suggestions appreciated. 73s Bill
