Zwift ride won't upload

So I did the stage 3 of the tour of london, kept going for more miles as I was doing a training ride and finished my metric century achievement (have a screen shot of it) only for zwift to screw up during the upload process when I finished my ride. As there are 4 Zwift fit files on my computer for today’s ride, which one do I try and upload to Strava? Is there a way to get credit for finishing the stage and my achievement?

Thank you

Here you can merge several fit files for your Strava upload.

You should have your 100km badge already. It’s ingame and doesn’t have anything to do with strava.
