Duplicate running splits in the app

[Unixcrucifix]

My splits in my Fitbit app are duplicating every time I go into the detail.

Just ran 4.3km, so I had 6 splits: 1 for each km, and 2 more for the last partial km( not sure why it does this)

Went into again, and now I have 12 splits. The more I go into it, the more I get that are just duplicates of the original. I now have 36, How do I stop this happening?

I have an ionic, and a Samsung note 10+, both running the latest firmware.

Welcome to the Fitbit Community, @Unixcrucifix.

Thanks for the details shared in your post. I recommend doing the following:

1. Log out from the Fitbit app.
2. On your phone's settings tap on Apps > Fitbit > Storage > Clear cache and then Force Stop.
3. Reboot your phone.
4. Open the Fitbit app and log back in to your account.

By the way, I've moved your post to Android App board so we can keep our forums organized.

Hope this helps.
