Why can't I draw another Insert Cylinder Hose without the 1st dissapearing?

[Betamax]

Why can’t I draw another Insert Cylinder Hose without the 1st dissapearing? As soon as I draw a 2nd Insert Cylinder Hose the first one dissappears. This happens over and over. Somehow I have been able to do it before but for the last hour it’s driving up the wall.

thanks for your time.

Just click on the mesh to delete the curve before drawing the new one (Or press Stroke > Curve Functions > Delete).
