I had The Wife push on them while I had them inserted and I was like "WOW! THIS is how I imagined them working!!"
.

I did everything correctly and the products do not work as they should. Hopefully it'll all get sorted out.
No offense intended, but these kind of comments (the bolded part) give folks the wrong impression about IEM's and those who make them. The vendors reputation is based on them working properly, and all they have to go on is your ear impressions.
This is NOT YOUR FAULT!!
"impression" being the key word here, as your OP about lack of seal indicates the audiologist didn't make good/perfect impressions! Wife pushing on them tells me the impressions did not cover the 2nd bend in the canal.
Based on my experience this goes back to the old computer adage.. "garbage in, garbage out".
If the impressions don't CLOSELY match your actual ear structure, they are NOT going to fit properly. Maybe one ear impression was good, the other not? idk.
But nothing JH, 64Audio, Alclair, Alien Earz or any other vendor can do will fix that, UNTIL you TRY them.
I've seen (and read) numerous instances (over the last 10 yrs of being IEM) where refits were required and every single instance was due to poor impressions.
That is NOT your fault nor the vendors!
No-one who gets impressions made can tell if they are a perfect replica of their canals.
You rely on the audiologist and their experience.
I guess I've been lucky with the sets I have had made.. going to an audiologist used by a mega-church! idk. But I've only had a problem with my 1st set (different audiologist), none with the rest!
Looks like a refit is needed (or use @Geri O's suggestion).
Hopefully, you WILL get it all sorted out soon.
Best of luck with it.
Keep us posted pls!
