Hi Tina,
Welcome to the Adobe Community!
Would you mind sharing some more info regarding the issue you're facing? A screenshot would be really helpful for us to troubleshoot the issue.
Also, could you please try enabling "Legacy compositing" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?
What version of Photoshop and the Operating system you're working on?
Regards,
Sahil
