bug with Black Studio TinyMCE usage

I believe I have found a bug with the recent upgrade to WP 4.8.1. With Jetpack v 5.2.1 activated, the HTML visual editor in Black Studio TinyMCE is disabled in edit preview. The plugin still displays properly on the website, but it is not possible to edit anything with the visual tab. When I disable Jetpack everything functions properly. I have updated everything to current versions, don’t know if this is bug for Jetpack or Black Studio.
