Is it possible to exclude Saturday and Sunday from Business days in Zoho campaigns?

I am running one workflow with 3 days gap as follows:
Starting Wednesday it should deliver on Monday

Starting Thursday it should deliver on Tuesday

Starting Friday it should deliver on Wednesday

But what is happening that instead of getting delivered on Monday, Tuesday and Wednesday, my all email is delivered on Monday after enabled send day from Mon-Fri.

Is there a solution for the same?

Thanks,

Arpit
