importing styles

[Mr. M]

I recently started using my PTE Essentials 9 and love it. I managed to import Lins snow styles and was very

happy with the results(even added music). I then tried Lins "large snow globe for 16:9 aspect ratio with more snow" with the thought

of putting a png image of my Granddaughter and her husband in it. But, when I tried to import it, I got this notification " a slide

with this name already exists".  "Do you want to overwrite this style?" with the options to overwrite or cancel. This has happened

a few times when I tried to import various styles. 

What am I doing wrong.

Thank you,

Moe(Mr. M.)
