GigaPixel AI not making files larger than 6mb? Help

Hellol, need help, just purchased a new MacBook Pro , excited to install Giga Pixel… did the download, installed. but the images are not larger than 6mb… where as previous computer they were files of 74mb or larger? help

When exporting the files, check the export file type. Trying using lossless compression like png and tif.
