Inset Image while using TinyMCE editor

Using Grav 1.6.0-rc.3 and relevantly updated plugins.

Using a page with TinyMCE editor and the Grav out of the box media facility for upoading image and other files.

When I click the “+” symbol to the right of the image file the Insert Image pop up gets displayed multiple times (around 6), I have to cancel them all to get the the first one displayed and that one contains the link to the file that I want to insert.

Hopefully this can be fixed in the final release.

Also just wondering if there is an estimate to the final production release date for 1.6, as I did as the site suggests and started building a new site in the latest version when it was in beta and that was quite sometime ago.
