A project is around 4MB in size, doesn’t look like anything is wrong. You should be able to press ‘Stop Rec’ and save the resulting file from the C6 window. Sysex transfer doesn’t flag (afaik) that the sending device is done, so you need to stop receiving manually.
After pressing Stop Rec you should see a file entry in the C6 window. Highlight that by clicking on it and then press Save to save the data as a .syx.
(As for the settings, should be fine to set the delay ticks to 0, it’s a lot faster and shouldn’t cause any issues)
