Flowchart clones the current arrowhead settings instead of setting no arrowhead on the start and arrowhead at the end

Steps to repro:
1.Select the arrow tool  and set the start arrowhead to any (ex. triangle)
2. Create flowchart (i.e. create rectangle and then Ctrl/Cmd + right arrow 2x)
3. The arrow goes <-> instead of ->
