Thread:Talk:Semantic Result Formats/Incorrect Sum if more than one property has same numerical value

On my wiki, Property:Regimen has type::number and is used on pages with.

If I have: Regimen::1 + Regimen::1 + Regimen::1 + Regimen::2 + Regimen::4 + Regimen::10 + Regimen::20 + Regimen::40

And

Then the output sum that's listed is 77, which is 1 + 2 + 4 + 10 + 20 + 40. It leaves out two out of the three Regimen::1 values.

This is a problem for me because I want to label various areas on different pages as [[Regimen::1] (or actually ) and then add up the number of times I used the label. Is this a bug, or am I doing something wrong?  Thank you.
