FalseStartToggle in Ladybug Legacy plugin


I installed the Ladybug Legacy plugin (latest version from Food4Rhino and Rhino7), but I get a “Unrecognized Objects” message for the FalseStartToggle component when I open a GH template containing this component (from another computer). Is this component only available in the Ladybug Tools plugin (and not in the Legacy one)? Or is there something else going on?

Thank you,
