OMG _ HEEEELLLLLLLLP

Why all of a sudden would my spreadsheet not reflect properly?

All my parent/child relationships are not showing - rows of information are blank. However when I export the file, the information is all there? example - parent row 10 displayed but not as a parent and child rows 11, 12, 13 are not showing - appear hidden but can't be unhidden??

How do I fix/repair this easily.
