I edited this post as I too found that using ESTmep 2020 my E-Times were reporting out 0.
I have 2024 on a VM for testing, everything worked in there, so I posted it works in 2024.
We use 2020, so I crapped my pants a bit, but knew that I'm reporting this out. So I reopened ESTmep to print the report but found the cost breakdown was working again.
Turn it off and back on.
The only other thing that I have done in this time was to delete the database from its location and paste it back in from the master location.
Not a work around I'm baffled as to why it wasn't and now is working.
