Uploading receipt: do I have to pay visa fee again?!

[thaaa]

Hello!

I received a request for paying and uploading a receipt regarding Biometrics.
I completed the payment and added it to the application.
But, when I'm about to sign and submit the application again, there's the same information about paying the $100 visa fee I had already paid when I transmitted the application originally! Am I going to have to pay that twice?!

For those having a similar issue, when you upload the requested document and try to sign the application, you get the information about the visa fee again, but you won't really have to pay.

I guess the system just has one "signing" page model, that doesn't provide different information depending on whether you are submitting the application for the first time, or just adding more files to it.

So, no double payment!
