If you load an empty RxnMolecule into a MSketchPane it initially displays an arrow in the middle of the screen. If you then start to draw a reagent and add 4 or more atoms the arrow disappears.

this also happens if you have a RxnMolecule with just a reactant (so there is nothing to the right of the arrow). Once you start editing that reactant the arrow disappears.

Hello, in the current state there must be a reactant a product in a reaction, but we are working on to extend the representation. So the result will be a more flexible arrow and multistep reactions but for the moment it is not possible yet. Still, we are considering this as a bug and trying to solve it for a minor release (4.1.7 likely).
