401k to IRA conversion - share price is WRONG

I converted a 401K retirement account to a rollover IRA. When doing the conversion Quicken came up with these outrageous share prices e.g. $11,439.00 per share. It was a different value for each conversion transaction, ALL completely wrong. On one of the funds I went in manually and changed the share price to the current price on the day of the conversion and selected "total amount" in the change process. THAT fund is now showing correctly. Is there any way to get the other funds corrected without having to manually edit each of almost 100 transactions? Currently it shows a "loss" of almost $500,00.00
