Please install the latest version. Some time next week there will be a latest version to be released.
It seems there is a display issue, which is unfortnate. If the issue still exists, please contact our technical support email with computer OS version.
As for the Matlab issue, I hope it will be resolved once newer version is installed. You may also find some suggestions here https://forum.ansys.com/forums/topic/connect-matlab-to-lumerical/
