Hi Mike and Everyone
Thank you to Mike for sending me the files - Mike is correct there was a small bug in the previous version with the Race headings when merging - This however only occured if the race order of the file being merged in had previously had its race order adjusted using the Move left or right, as far as I can tell.
Many thanks to Mike for finding and reporting this.
It is fixed in version 2.29.6 which can be downloaded from https://www.dropbox.com/s/vx5bdhije0sq3xp/sailwave.exe?dl=1
This is an exe only so you must have 2.29.0 or later installed and then replace the Sailwave.exe file with this newer version
Mike - let me know if this fixes your issues.
Hope you all had a good Christmas. Happy new year
Jon
