The linking code you have for these galleries is incorrect.
Mzk6NToy is the linking code you should have at the end of your URLs if you want to send to THH... As you can see you have one gallery with the correct linking code so this is giving you the SOMETIMES it works and SOMETIMES it doesn't issue.

Each site and each campaign and each program has its own seperate code. You will want to check that before anything. As these pass through and will cause these errors.
Thank you Buddy for helping out on this issue.
