That's not good enough for the reasons you describe. Although it's unlikely to rotate by itself now because it has lifted the corner of the black plastic flange near the end of the spring so that's probably going to hold it in position. Not ideal.
If taking it back to the shop is a long way, you could try and fix it yourself by winding the blue ring all the way down to the bottom of the threads with the wheel in the air to unload the spring as much as possible. Count the turns. Then you might be able to over-rotate it, push the little corner flap back down with the tip of a screwdriver then try and rotate it back into the correct position.
If you are successful with that, you can wind the perch back up the same number of turns then add a bit more to compensate for the now correctly seated spring. How much further? See the diagram below. Take the vertical measurement then add enough turns to bring the perch up that much.
