Privacy Zones mess up target pace graph

One of my Garmin friends is following a DSW running trainings and has a privacy zone established. Because of that, beginings and ends of his runs are not visible for me. 

What's strange is that Garmin Connect on Android displays correct pace data (for the middle part of the run) but the target pace graph is off (it starts from the very beginning of the training). This is how it looks like on my side:

The web version shows this correctly:

And for reference, this is the complete pace graph without privacy filtering (taken from my friend):

Is there a chance to correct this issue?

Best Regards,
