Office ribbon not selecting default option

[jamie.lunam]

Hi all. I have a perplexing issue. I have recently upgraded to MS Office 2016 and when clicking directly on the options in the ribbon it is not applying the default, but instead forcing me to select a choice from the respective drop down. It is making me crazy!



Hopefully my screen grab has attached in case you need any clarity on what I am referring. The example shown is where you might just want to quickly turn text to any colour and therefore you are happy with the default red, but rather than it just doing it, you need to choose a colour from the drop down menu - where is this secretive setting hidden!

It is happening in all office products in my new install.
