I noticed this first in Q10 but but found the same issue in Q7:
I have a paycheck set up one line in the paycheck showing company paid insurance benefits being transferred to an insurance account. After viewing a tax report, I found I had used an income catagory instead of an expense for the transfer so it was being counted as income twice.
I created a new catagory under insurance and used the EDIT/REPLACE function to change the catagory of the transfer line in all affected paycheck entries. When this finally finished, I found most (but not all) of the changed paycheck entries in my registry had all the details missing. The tax report now shows near zero salary for the year.
I restored a backup and tried again, doing the same thing manually one paycheck at a time. After a few changes, I check and sure enough, the paycheck details were wiped out.
How do I change the catagory of lines in a paycheck in the register without wiping out the paycheck details?
