Grading assignments using Kami on dual monitors

I am creating assignments through Kami and then putting them in Google Classroom. The students are then able to do their work, submit to me, and then I grade it using Kami. Works beautifully!! Today I added another monitor so I would have two screens so I can have an extended screen which also works great! However I am having a problem with grading assignments using Kami if I am using both screens? Weird for sure…I tried just using Kami to write on with the double screen and it works fine so it is something to do with grading using Kami and the extended screen. Hopefully someone can help me.
