“Vector Limit Reached”

Hello!

im fairly new to adobe capture, but it has been really useful in cleaning up my black and white drawings, getting them ready for prints and cards..

im trying to do a postcard for a restaurant, and I can’t save the finished product bc ‘vector limit reached’. I’m frustrated bc the image doesn’t even have color, and it’s not as complicated as my other drawings have been. I don’t know how else to refine my drawings to get them ready for the printing people at a high resolution! And this has only happened since the app updated. 

Any help or advice would be much appreciated!
