Text keeps resizing on button hover
I'm having an issue with a course i've started to put together, i'm hoping someone can help me with.
I have a number of buttons (shapes with text) on the slide master, each has a hover state on it which is basically the same item nudged up a few pixels.
In the states the text on each button is the same size however when previewed or published the text changes size on the hover state.
Initially i thought it was me so started again and recreated them but i get exactly the same issue each time.
Has anyone got any idea whats wrong please?
