Custom datafield crashes in certain activity profiles

Hello,

This is my first post at the forum, so if it is not at the proper location, please, let me know.

I've created a multiple datafield for Garmin Edge 530 and after some intensive test in beta version, i've finally published it (Bolet Power).

For testing purpose I created a specific activity profile in my device where I have been using the beta version. The "production" version still works on it, but if I try to include this same datafield in my MTB profile, it crashes. If I create a new profile based on that old MTB one, it works again.

I can use this woraround, but my concern is that anybody who downloads my datafield will discard it immediately if it does crash with their old activity profiles.

Any idea about what can be causing the error and how to solve it?

Thanks!
