Odd tie behavious using grace notes.

I was adding slurs and accents/staccatos to the piano part.

I had placed the grace note in the 1st bar of the first ending.
I add the ties and moved the g. notes to the left to lengthen the ties.
Before I moved the notes the lowest note and the note above it had appropriate laid out ties but the top note the was just had a very short "hat" over it. (It was the tie).

I then went to each tie and moved their start point to the left to draw the tie extensions from the bar before the 1st ending. I was successful.

I went back into the piece and added a few more slurs and a few missed staccatos and zoomed out. I noticed that the ties in the 2nd last bar were not visible.

I reapplied on the top note and the 2 lower notes appeared. I reapplied on the top note again and the result is in the attachment. (The adjustments to the ties had not been kept).

Can some one help? (attached)
