Bug Profiler showing 0 draw calls and 0 set pass calls for older version of unity scene

We recently updated our project from unity verison 2021.3.3f1 to 2021.3.13f1 but our older scenes when checking in the profiler are showing 0 draw calls and 0 set pass calls , it sometimes gives a spike for render and shoes the correct data . if we create a new scene in unity it is showing the render data on the profiler correctly . Can someone have any idea why this issue is happening and how to fix this . our game is for the mobile platforms so optimizing this data is really crucial for our development

 

Hi, what does Stats overlay show to you?
I can see that some stats (memory, buffers, etc) are non zero - could it be that the frame was not rendered?
If not - more likely it is the stats synchronization bug.

 

I am getting same issue. Is there a solution. Unity version is 2021.3.18f1

 

In Unity 2021.3, I faced the same issue where the Rendering section showed a lot of frame is 0 draw calls while the Stats FPS remained stable.
After investigating, I found that setting "Application.targetFramerate = 60;" was the culprit. Although it might be considered a bug, I resolved the problem by avoiding the execution of "targetFramerate" within the editor.
