Skype is currently in a period of transition and I guess the idea is for Microsoft to invest in restoring functionality 'overtime' it needs to at least get everyone on the newer releases. Please follow the steps below on how to download the classic Skype. You should file this as a bug report,then reinstall the classic version. The new Skype is very new and lacking certain features and functionality.
Microsoft has listened to customer feedback and is allowing users who are comfortable with Skype Classic to continue use it for the foreseeable future until all the issues in Skype 8 are sorted out. I recommend you go back to the classic version, since a lot of the functionality in Skype 8 is still maturing. Unfortunately, that is not possible, you can backup your entire Skype conversation history.
