Duplicate Checks

We recently created a check; it was somehow duplicated the 741 more times! Has this happened before? I talked with Sage, they said I would have to go in and delete them one by one. It did not copy the vendor, only the check number and date with a $0 amount. The original check number is 11869 then it goes 11869a, 11869aa, 11869aaa, 11869aab all the way to 11869zz. 

Sage suggested restoring a backup but then I would have to try and reenter everything since then which isn't going to happen! Does anyone know of an easier way to group delete them? If not I will just leave them there, which makes my reports super long!
