Printed gears stick together

[raylo32]

Not having any luck with this in S3D and I don't understand the settings in FlashPrint.

Here are snips of the model list from S3D of the base model (only 1 model listed) and after I have gone into mesh and separate connected surfaces (like 25 models listed??). Clicking on any of the multitude of models does nothing except the first which deletes the whole thing... and one other one that simply changes the color of the whole thing.
