For some Users, few types of Reports are coming in striped colors instead of solid colors.
This is not an issue, it's is related to User settings by which the color format pattern changes in Reports.
For User who have 'Data Visualization patterns enabled' (in Settings) will have the reports shown as Strip colors.
Please follow below steps to fix the issue.
- Go to Settings (Gear Icon - you can find Settings icon on top right corner on Banner frame) of User.
- See 'Data Visualization patterns enabled' field in General (in Settings).
- Disable this field as shown in screenshot to see all the reports in Solid colors.
Once done, reload the session to see the Reports in solid colors as below.
