it happens if you have a crossed feeder towards the antenna.. check it simultaneously.. I mean, have someone upstairs to check the feeder connection.. try to do DTF with a dummy load to see which feeder you are testing. if he picked the wrong one, of course you will get a VSWR of the whole antenna system.. so you'll have to do it 1 by 1.. the cell A TX/RXA leg is not paired with Cell A RXB. it means the right diversity is paired with the other sector..

In ericsson 2G cabinets,we usually gets alarm for RX diversity sometimes even when we use both ports of antenna.It is npt service affecting but how can we kill this alarm.
