Stationary lights in blueprints

Hello, I have a blueprint where I can set up the lamp with light. There are a few different lamps, so I need to change the position of the light. But when I change the lamp mesh with stationary light, It shows me a red cross. It happened only with “set relative location” block. This can be fixed by changing stationarity to another and back to stationary, but only manual, not from the blueprint. How do I need to do this properly? Or it will be better to create few blueprints with different mesh without dynamic changing mesh in the scene?
