Hi @kleberfonseca,
Not recognizing sparkline formatting for the total row is a known issue and will be fixed with the nearest eazyBI version. I am sorry for the trouble this is causing you!
Meanwhile, you can check a workaround here Hiding markdown in row totals - #2 by roberts.cacus.
I was not able to reproduce the second question. If you still have issues with that, please, export the report definition and send it to support@eazybi.com.
