... that you are confused.......or I am

You mention making an online application via VFS, so I've got to assume that
you are in the Philipinnes.

.... these fees apply in the UK.

Why would someone applying in the Philipinnes pay in £ sterling ?

The fees for fiancee / spouse visas in the Philipinnes are quoted in PESOS on the
VFS site.
These are the ones you need to adhere to.
