Member can't create see a list but all others can.

Invited a new employee to a board and added them as Admin. They can see all lists but 1. They can add a list  and all other members see it but not the one who created it.

The go-to piece of advice is to try opening Trello in either incognito mode, or from another browser.

If it happens to work there, its usually caused by a browser extension or adblocker acting up, and you can flick them on and off to narrow down which one is causing issues.

I appreciate your input/suggestion.

I did notice an unusual extension on the members PC but after removing it the list was still visible. Turns out there was an odd, barely visible, toolbar along the bottom of the board. After investigating I found that it would allow a user to hide/unhide lists. I use a similar one for my PC but I didn't recognize this one. All I had to do was unhide the list in question.
