Return of Capital for Incitec Pivot (ASX:IPL) - how to handle in Sharesight?

Today IPL have released a $500 million Return of Capital via a $0.1557 per share capital reduction.

I’m wondering what I have to do in Sharesight to accurately reflect this? At the moment I have an automatic notification in the UI of a negative $$ balance of the value of my holding that the app wants me to approve, but shouldn’t the reduction in capital per share show a positive increase in the value of my holding?

I have also purchased multiple batches of shares for this company, so do I just go in and edit the ‘buy price’ down or something?

Am confused with the way Sharesight is attempting to handle this.

Thanks.
