Welcome to the Community, JuanJHAccountants.
Issues with saving your customized Management reports can be caused by a browser. Let's try using a private browser or incognito window as an initial step on fixing this issue. This will eliminate any browser history that may cause a glitch inside QuickBooks. You can refer to the following keyboard shortcuts below:
- Google Chrome: Ctrl + Shift + N
- Microsoft Edge: Ctrl + Shift + P
- Firefox: Ctrl + Shift + P
- Safari: Command + Shift + N
Once done, try customizing the report again, then close out the private window and clear the cache on the regular browser. This will remove previously-stored browsing data that might have caused the issue. Otherwise, you can try other supported browsers to help narrow down the cause of this behavior.
I've added this great resources for reference in case you want to learn how to customize reports in QBO: Customise reports in QuickBooks Online.
