Power BI Report - Visualization and Data Fixing

I need assistance with my Power BI report due to some visualization problems. The main issue pertains to formatting, specifically with data labels.

Data:
- Pulled from a SharePoint List

My Issue:
- Unable to show the Assigned To (User Name), it just shows AssignedToId
- Am using a data card but not user friendly, it doesnt show easy date navigation
- I cannot use modified by in Power BI

Please connect only if you have expertise to resolve above.

Thank you
