Asset addition issue

My agency recently uploaded around 20,000 assets into E10 through DMT. Previously we had been using a proprietary system designed many, many years ago. Unfortunately some of the data in the old system was not correct and due to the amount of data uploaded some mistakes made it through.

Roughly ten of our assets had incorrect Cost amounts and Previous Years Depreciation amounts. These were entered as MISC additions and Inter-Group transfers. What is the best way to make corrections to these assets without wreaking havoc on the General Ledger?

EPICOR support suggested just disposing of the assets and doing manual journal entries to wash it out. This worked for roughly half of the assets, but the other half are getting stuck in Review Journals because the Debits and Credits that EPICOR is creating for the disposals have a .01 variance. Support was unable to assist. Has anyone ever seen this before?
