Landing Gear Issue

[JAG]

I am really focusing hard on the words written to try and figure out what is going on. I have some confusion as some times he talks about "retraction" associated with downlocks and "full up". Is this just a mistype, or am I not understanding this post?

My understanding is that the sometimes the LEFT Main gear is not able to fully EXTEND (read DOWN AND LOCKED) as it is coming into contact with the downlock pin before it is fully seated in the saddle.
