User opens planning form in Excel and not all columns show up

I have a user who wants to use the Planning forms in Excel rather than in the workspace. She opens the form in Excel the first time she sees everything. She changes the account and January through May columns disappear. If she opens the form again, not all the columns are there. It does work fine for her in the workspace.

I signed in as an admin on her machine and the form works fine. I signed in on my laptop as a test user with the same security as she has, and the form works fine. Other users have no issue with the form. It seems to me that there is some setting on her machine that is causing issues. I am not sure if this is a smart view setting, an excel setting or possibly an internet setting. Has anyone else seen/solved this problem?
