SWR - Standing Wave Ratio - does not tell us if the antenna is resonant or not, it just tells us what the feed line is doing...

Start at the antenna end, hook up a true 50 ohm dummy load, turn your transmit power down to 5 watts and key the transmitter in CW mode. Adjust the meter so it reads zero...

Read what the SWR reads on your meter at the transmitter side of the coax in several different band positions while it is connected to the dummy load at the antenna end.
If it jumps around, then you probably have a feed line problem.

Did you check the power output of the transmitter into a true 50 ohm dummy load the same way?

I once had a bad jumper going to the SWR meter / coax switch, that caused me a lot of problems.
