Pre-fill incorrect at W1 when salary sacrifice to super?

Good afternoon,

I am finalising BAS and the pre-fill at W1 includes an amount that has been salary sacrificed in full to the employee's superannuation. When attempting to override W1, an ATO pop-up message states it differs from STP amount already reported.

Could I please get some advice on my set-up of this superannuation pay item, as from what I have read I don't think it is reporting STP correctly. ATO advises the amount at W1 should be the post-sacrificed amount, and in this case the entire amount was sacrificed to superannuation.

This is most likely the way I have set up the superannuation pay item, but after looking through the forums, I can't figure out where I've gone wrong, and would appreciate some assistance.

Thank you and kind regards,

Nal

Edited to add further detail in case it's required; this is for STP2, the salary sacrifice was set up under the supannuation tab, the employee chose to forego their entire salary as a pre-tax deduction, diverting the whole amount $10,500 to their super fund, which was successfully paid, along with their usual super guarantee. The issue is the amount is showing at W1 in the ATO portal.
