Need to delete multiple lines in cells but keep one

Amazing, it works almost exactly right. There is only one problem.

1. The red dates and italic dates after strikethrough dates are being deleted. See rows 21,22,23,25,51 column o (format?),61,62,64,and others -- AFTER RUNNING THE MACRO

I posted the updated file with the improved macro. I included in the file the desired results and the original info.

The last thing to fix is to keep the red and italic dates that follow strikthough dates or that are the first line in the cell.

Thanks for all the help. Almost Solved!
