Multiple Tags on Opportunity results in duplicate records in reports

Hi all

I might be something wrong - and if I am, please point it out

Ok, I´ve made a summation with details report. Works fine. Then I was asked to add the Tags name as one of the display column. Did that. Then we noticed that records with multiple Tags show up multiple times (one time for each tag). Here is an example of record with two tags:

Not only is this confusing/wrong but this also skews the total amount in the report, see the red circle. Each opportunity is added up in the total of the Display Summaries.

Anyone else running into this and has a solution?

Or is this a bug?

The column "Tag" I use in the Display Columns, is Opportunities - Tags - Name

Thanks all,

KGM
