Sounds like the known limitation for LightMix with the ShadowCatcher, as listed on https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180-known-bugs-and-limitations (https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180-known-bugs-and-limitations) ?

I don't find there as a know limitation.
Simply: on lightmix, when i turn off the light the shadows remain on plane with CoronaShadowCatcherMtl.

The limitation on that page is listed as:

"LightMix (3ds Max | C4D) does not interactively update shadow catcher material shading results.
Solution: use the ">Scene" button in LightMix to bake light properties into scene objects."

So it would be impossible to turn a light off in LightMix and have the ShadowCatcher update, as the Shadowcatcher doesn't update with LightMix changes at this time.
