Ribbon Customization unstable

Question

I have created a small ribbon which (in theory) 6 items on it: 
 
 Save 
 Save As 
 Save Target As 
 Translate Single Document 
 Commit Changes 
 Options 
 
 However, 3 and 5 are not stable. They disappear and re-appear at random. I don't mean that they get greyed out (I know this happens when a particular command is not available in a certain context) but they disappear completely from the ribbon. 
 If I go into view options, sometimes the item is still there but the tick has gone (most often happens to Commit Changes), sometimes the entire item has gone (most often happens to Save Target As). 
 Win8, Trados Studio 2015, all updates installed.

 I tested your combination and found out that it works fine. 
 The confusing thing is that the two commands you mention show up only if you are in the right context, meaning if you are in the Editor (for "Save target as" and in the "Translation Memories" view for "Commit changes"). In other words, instead of being grayed out if they are not applicable, they are not displayed at all. 
 I agree that this can be confusing. It would be clearer if they were grayed out. On the other hand, I can imagine that this has been done by design in order to make best use of the space available in the ribbon. 
 Commands are grayed out if they belong to your view, but are not applicable. If they are not available at all in your view, they don't even show up. 
 Once you know how it works, there is no problem anymore.
