         Before submitting a **Bug Report**, please ensure the following:
 
-                **1:** You are running the latest version of ComfyUI.
-                **2:** You have looked at the existing bug reports and made sure this isn't already reported.
-                **3:** This is an actual bug in ComfyUI, not just a support question and not caused by an custom node. A bug is when you can specify exact steps to replicate what went wrong and others will be able to repeat your steps and see the same issue happen.
