Estimation and time spent for the issue

I need a report to monitor the estimated and spent time as part of the task in the context of user groups (analysts, managers, developers, testers). To account for estimates for each of the groups, I added 4 custom fields for entering the estimates of labor costs for each of the groups that I selected as a measure in the report along with the column Spent hours. But when adding the Logged By Group column, these ratings are split up and duplicated. Can this be avoided?
Below is the title of the report table. The first 4 columns are estimates for one of the groups, divided by groups again, and the fifth is the hours spent in the context of the task by group.

Thank you in advance.

Colleagues, please help.
