Cannot connect node ?

[lalalandsynth]

Tried , closing and opening project .
Tried removing modules, adding again.

It will not allow me to connect this ?
Ramp to Input toggle value 2, cannot connect anything to Value 1 as well.

Does not happen if I make a new project.

Managed to make this work by adding another toggle on top , connecting to that and then deleting the old ones.
