Error "Column doesn't exist" when it does exists

When I run UFT One script, it gives an error "Column doesn't exist" when it clearly exists. 

According to the official UFT One documentation sheets should have same names as actions. I followed this rule but nevertheless UFT One doesn't see ZV60 sheet. It only sees FB60 sheet. All other parameters from ZV60 sheet aren't recognized. 

Attached a screenshot with details.

What might be the problem?

Any advice much appreciated!

Thanks, 

Masha
