No, it's not paradoxical at all.

In the moving frame, the clocks at A and B were never synchronous.
Thus the fact that the clock that remains at B (and therefore moves
with respect to your clock which sits while points A and B wash by) is
ahead of the other clock makes perfect sense, physically.

There is no paradox.

There is only your superficial and oversimplified understanding of
what relativity says.
