show items with no data as 0 instead of blanks

Just a little background on the above table:

Project Name, Category Name, and Portfolio Name are from a table called 'Projects"

Actual, Committed are from a table called 'Expenses'

Projects is a one to many relationship with Expenses

In the above scenario, the project "cancer test project 5" has no related records in the Expenses table, so it is showing as blank, is there a way to show 0 instead

I have tried doing the following in the Projects table, but it gave unexpected results:  Actual = IF(ISBLANK(SUMX(RELATEDTABLE('Expenses'), [Actual])) = FALSE(), SUMX(RELATEDTABLE('Expenses'), [Actual]), 0)
