Thank you for bringing this to our attention. We need to fix this.

... But just a little hint for your design ... If you'll try to stitch this out, it won't work very well. Satins that small will be a pain for the embroidery machine and the fabric. Consider to use running stitch instead.

Thank you! And yes, I realized that when test running it on some scrap fabric :/
