Transformation Switch

I faced a problem, when drawing path is loosed on some frames. Can’t correct it choosing drawing from the list, cause properties of Transformation Switch node looks different than in this description

https://docs.toonboom.com/help/harmony-14/premium/reference/node/combine/transformation-switch-node.html

When open this properties I can see only “Drawing Path” (which is read only) And names of drawings
I was looking in preferences, but unsuccessful

Could You help m please, how can I fix this?

Thanks!
