Hi @malioto,
Welcome to eazyBI community! 
Measure Original estimated hours are counted only against the issue’s current sprint. In this case, if you have issue that is being done in several sprints then Original estimated hours will be shown only at current sprint level. (you can read more about Jira software related measures here - Jira Software custom fields)
If you would like to calculate Original estimated hours for issues committed to a Sprint then I suggest checking this answer from my colleague Zane:
