xp2 file numbering question?

I use Lightroom CC 2015 and use a formula for file naming that looks at the model camera and then adds it's name followed by the file number from the camera.

It has worked great for every camera I've owned ... so far. The XP2 adds an extra 2 so that I'm showing that I already shot 21900+ images instead of 1900+

example of number and file template below.

Any idea how to change/correct this? View attachment 86350 View attachment 86351
