There is a way to get rid of the columns (Act. Cost & Act. Sales Price) .... on the report display, at the top of the column where the column heading is, there are 3 vertical dots. Click & Hold on those 3 dots, and then drag them to the left just past the left edge of the column and the column will vanish from your report. 

----- Don't thank me. FishingForAnswers is the one who gave that method to me, so he gets the credit.

However, you need to check reports very closely, because it appears that QB's crack design team has fubar'd  many reports: standard reports and memorized reports. What I've seen so far is that many times when either or both of the "surprise columns from QuickBooks" (Act. Cost and/or Act. Sales Price") appear on a report, there is some column that used to be on the report that is no longer  present, so just removing the one or two "surprise" columns won't fix the report. You need to examine the report to see if it still displays the data you expected to see. And I have yet to discern any consistency in what reports are infected with this "surprise" problem ... sometimes I have been missing a column that used to be in the report, sometimes it is just removing the "surprise" columns. Sometimes it is a memorized report, sometimes a standard report.

Not only are there "surprise" columns, sometimes it is a "surprise" as to which reports are infected.

Everyone who has responded to this in the past AND all that respond in the future should ALSO go to HELP, and under the "Submit Feedback Online", please submit a Bug Report to describe this problem. QB will not respond when only one or two people complain or submit ideas. But if enough of us do bombard them with Bug Reports and complaints, they just might be tempted to try to figure out how to undo their FUBAR.
