Two tables different numbers

Hi,

I am having trouble with numbers from the two different tables below:

The values circled in purple should be the same in both tables. However, they are not.

The formula for the first table, for "Total: " is: ="Total: "+ Sum([Days Between W.O. Open Date and Forward TPS_CONFIG])

The formula for the second table, for "Total:" is: = Sum([Days Between W.O. Open Date and Forward TPS_CONFIG]foreach([W.O.]))

I don't understand why this does not reuslt in the same numbers. Both filters are the same. And for example, column #2 is right in both tables..

Thank you !
