None of your parents where changed. Your whole issue for the majority of this thread is you had not done your cleanup work noted in the instructions which I explained before. Once your clean up work was done all categories appeared and where under the proper parent etc. Alot of the issue you see is differences in Photopost from Coppermine. That confuses alot of people.
We store all the info as it is entered in coppermine but how we do things is not exactly like coppermine.
