Ugh, my new Sheaffer Snorkel

I just received my new Sheaffer Snorkel. I filled the pen with water. Unfortunately, the tube won't retract after filling. I will await a reply from the seller. Yes, I'm confident the seller restored the pen. Worst case, I send it back and seller fixes it. Likely an easy fix. Thanks for listening.

I remember something about that in grandmia's (penkino1) video on the Snorkel restoration. It was something very easy to miss and that could happen.

Thought this would be more appropriate to go in the Sheaffer forum.
