You should remove that column "Chromatogram Precursor M/Z" from your report.
That column causes Skyline to give you one row per transition. If you remove that column, then you will get one row per precursor which will be fewer rows.
If that does not fix your problem, then you should send us your Skyline document.
In Skyline, you can use the menu item:
File > Share > (complete)
to create a .zip file containing your Skyline document and supporting files including extracted chromatograms.
If that .zip file is less than 50MB you can attach it to this support request, otherwise you can upload it here:
