Since the cause of the first leak was a defective rubber seal, it would have made sense to replace all of them. I’m pretty sure they didn’t use different types of seals on each thruster port. But for that, they would have had to disassemble the spacecraft and that would have taken too long for the available launch windows.

It’s a good thing rubber seals have never caused any problems in spaceflight
