Issues with master layer fonts

Hello,

I'm wondering if I am the only person having issues with Master layer fonts..? I have created a number of Master layers with placeholder text boxes in them. For example, one Master layer has a "header" text box with the font-family: Frutiger LT Std 45 Light and font-weight: bold, as well as a "body copy" text box with the font-family: Frutiger LT 45 Light and font-weight: normal.

My issue is that when I exit the Master View and create a new slide, from the above mentioned master slide, the formatting seems to change without any input from me.

The "header" text box now has the formatting: font-family: Frutiger LT 45 light and font-weight: normal, and the "body copy" text box has the formatting: font-family: Frutiger LT 45 light and font-weight: bold.

Has this happened to anyone else?
