Unable to select cells in a table

[tsnouffer 3]

I'm running EN on my Mac (OS 10.13.6). It is the latest version of EN. I have a note that is just a table. Four columns and a few dozen rows. Recently, I've been unable to select cells within the table. It is hit or miss. A few cells I can select by double clicking or click and drag. Interestingly, in the rows I cannot select I also cannot add a row using the "+" on the left side of the table border. I can edit the text and color of these cells though.

I've tried copying and pasting into a new note with no luck.

If the table corrupted or something like that. How do I un-corrupt it?

 

Thanks
