no it's not normal. at least, from the photo you sent it isnt.

can you stand back and do a full on shot?

it appears to be down too far

here's my pocket door that we did.

I painted the upper inside track black so it's less noticeable.

outside.

This is another we did. rough in fitting

as you can see, the track is completely hidden.

I remember thinking there was a slightly bigger gap below as well. I’m not at the house, but I will send one over later this week. I had a feeling my contractor did something wrong or the door frame is off.

Yours looks great, thanks for the pics and comments.

Aside from the gap..........appears that when thee door is fully closed, you will still only see a part of the left trim ON the door. If that. Show the door fully closed
