This is working as intended. You can replace the repeater with redstone dust to fix your door (you'll need the repeater set to 4 ticks on the path (instead of directly pointing to pistons so that the timings are correct). The bottom piston should have never extended before, because it wasn't getting any power (piston is transparent so it won't power the piston below, and the block beside the bottom piston is not powered). However due to a bug in Java and Legacy console editions commonly known as "quasi-connectivity", it was extending because "if it was one block above its current position it would have extended". Bedrock code base does not have this bug.
