radgrid edit form template weird display issues

[ADT]

I have a radgrid that uses edit form templates. I open the grid and have all the fields in edit mode and hide the actual item row, to show only the edit item templates. I use a dropdown and textbox to have them choose a distributor and the # of records. In testing I generally use 10 #'s. When the button is clicked and the grid is populated. This form is used almost in the way that access forms are used, so they can input lots of records at once without having to click submit/add new over and over.

I am having an issue with the actual template itself, sometimes the fields go into weird positions and do not line up like the others. This can occur randomly but generally occurs after I click save and usually only occurs on the second to last record.

Anyone have ideas why this might occur? Would it be better to use a custom user template instead (can I still have this functionality with that)?

I will post my code below:
