Story Points closed not showing correctly when sprint is closed

I have a report that uses Sprint as a page and Story Points closed (we track two closed status) to calculate daily velocity for my teams (that uses a custom field property to select the correctly assignees). The problem with is that we loose the correctly measurements when sprint closes, showing numbers that do not match to what was actually done into sprint. Digging further I found that taking the Sprint dimension out of the report starts showing the correct numbers again, as story points closed measurement shows correctly daily information. So my question is, how do I keep this report running well for closed sprints? I am providing the bellow screenshots to help describing it. Sprint 25 run from Jan.28th to Feb.11th, so in my mind this would need to show all correct days in the table, and not just Jan.28th and Jan.29th.
