SUM is summing the whole column in each row of my table visual

[mxfx]

I have 2 almost identical tables in my query:
Table 1, "Prepaid units";

Table 2 "Consumed units":

When I build a table in the report, if I use sum of "Consumed units" I see the data normally, but if I do sum of "Prepaid units", it shows the total for the whole column

**please note, I cropped out the column on the left which reflects different Microsoft tenants for confidentiality reasons but imagine it's Tenant A, Tenant B, etc.
As shown above, instead of 43,800, I'm expecting to see 7,300, why is it behaving "normally" with Consumed units but not with Prepaid?

Thank you

These are great and very helpful, thank you very much.
Although it did not provide the exact "solution", it did help me understand what I was doing wrong.
Thank you.
