Mouse scroll stopped working on only some sheets within workbook

[teriellen]

I have not been able to figure out what I have done to stop the scrolling feature using the mouse. I have sheets for Monday - Sunday that won't scroll. Other sheets with different formatting scroll fine. I've checked to see if I can Unfreeze, but the sheets do not appear to have frozen panes. Any help would be appreciated! 

Here's my document.

@teriellen Unhide all the columns to the right of column N and all will be OK! Done that on the Monday sheet. See attached.

@Riny_van_Eekelen I still can't scroll with the mouse. Interesting that you can.

I was able to unhide the ROWS and was able to scroll. Thanks.
