first row not visible in Excel 2016

Hi, not sure if this question is in the right place...

I have a data file where the first row is not showing up. Yes, some of the panes are frozen. I have tried a few things but none of them have worked. Because this is sensitive data, I can't just post pictures here. I could send them via PM. Thanks.

Our PM system does not support file attachments. Our thread posts do. I recommend you remove sensitive data or replace it with a minimal amount of dummy data to demonstrate the problem.

Try using Ctr-A to select everything (or click the box to the upper left of Cell A1) and then set the row height to anything other than 0, by either right-clicking the row labels and choosing "Row height" or by hovering over a row boundary in the row label area and clicking and dragging when the cursor changes to a double-headed arrow icon.

Can you share the sample file also??

Even if the PM system did support attachments, you should NEVER share sensitive data with an unknown third party: you don't know any of us, and I suspect you'd be in breach of data protection measures if you did.
