I can't modify styles in Word Online

Andrew_1079 The only way that you can modify a Style in the Online version of Word, is to select some text that has the required attributes and then access the Styles Gallery and right click on the Style and then click on "Update [Style name} to match selection".
This fails to work with any style not showing up without pressing the down arrow because when my screen looks like yours my update to match selection choice appears behind the window which makes it impossible to use.
