Not execting the first step

Hi all,

I am facing an issue with one of my model flow.

when I am trying to execute the flow in productiion environment,the first step is not executed. instead it goes to second step.
is it the problem with model package? Will a regeneration be effective.
I couldn’t dwell into the problem since we donot have any access to prod server.
But in development environment it is working fine.

Anyone have faced the same issue before?

Thanks for the valuable feedback,
