I wasn't happy with the contact it was making so I put an additional bridge wire across that connecting point to insure contact was being made. Could that be a problem?
Yes, it could be a problem. The performance of the antenna is based on the diameter and spacing of the two wires that go from the UHF section to the CB-8269 black housing. It probably wouldn't be a problem if it was DC current, but those wires are for RF. The diameter and spacing of the wires determine the impedance of that transmission line, but it is difficult for me to predict how much difference it would make.

I don't like the way the forks on the circuit board make contact with the wires either; I consider it a design weakness of an otherwise good antenna. Most users don't have a problem with that type of connection, but some (like Nascarken) connect a separate balun to each section of the antenna and use an external UVSJ to combine the sections or separate feedlines from each balun and an A/B switch.

Winegard has a video to troubleshoot the CB-8269.
