Hi @Anonymous,
Could you please share a bit more about your scenario?
Do you create a PowerApps app for your SP list?
I have made a test on my side and don't have the issue that you mentioned. Please check if you have deleted the associated PowerApps app from your PowerApps environment.
Please take a try to clear cache of your browser and try the app again within your SP list, check if the issue still exists.
In addition, you could also take a try to re-create a new PowerApps app for this SP list on your side, then check if the issue is solved.
Best regards,
Kris
