Help me check a fit file containing pauses

Hello everyone,

I am new here in this forum to ask you some help to understand if/why some fit files are well encoded or not, corrupted or not, containing all infirmations or not.

I am using a desktop sports software (MytourBook) to generate some fit files to upload them to my native Suunto plateform (sorry, i am not a garmin device user ;) )

When those activities are containing pauses, Suunto ecosystem is having issues (activity replay seems not to consider the pause).

I am not a coder of any kind, i am just using FitCSVtool from the FIT SDK to decode those files, understand what i can see, try to modify things manually, and reencode to see if i can "fix" the issue in Suunto.

I didn't manage, so i am asking any help from you, at FIT file level : is there anything wrong with this file "content" ? is it not following any specific rule, or corrupted somewhere, or....

Thanks in advance for your help, i am willing to learn and help Mytourbook developpers to make those fit files more compliant (if the file is faulty).
