Problems with Korean-English input switching after update

I was using the Jump Desktop to connect to the MacMini in Windows PC.
After the recent update, there is no Korean-English input transition in FullScreen state.
(Not primarily working with FullScreen)
I tried with two windows PCs, but I can't switch to the same Korean-English input.
If I delete the jump desktop and install it back to the previous version, I can enter the Korean-English conversion.
I would appreciate it if you could let me know how I can switch from FullScreen state to Korean-English input in the update version.
