There shouldn’t be a difference. Are you sure all the other data is the same (previous dives, gases used)? The calculated heat map looks very similar which makes this even more surprising. Would you mind sharing the relevant part of your log with me (helling at atdotde.de) so I can have a look? In the recent version, in the dive export you can strip out the text data for the export.
