About button component submit parameter behavior in an interface

Hey,

I have an interface with multiple interfaces shown up using showwhen conditions.when i click on submit button on the screen then only the process should be started, in the same interface I have file upload component with another submit button , when I click on that submit button the file should be uploaded to the target folder and a process need to be triggered , in the same process i'm using uploaded files ID so i kept submit true.

Here I'm facing the issue, when i click on the uploading file submit, the screen is submitting directly and trigerring other process model.Just because submit true is also applied for second submit button.

The entire interface is a start form for one process model and there is  another process model triggered using startprocess smart service in uploadfile submit button.

Thanks in advance.
