Firstly,
I don't know what the selector is on. I did a galaxy reset so there isn't a previous game to highlight

Second,
When I look at a creation in the sporepedia the buttons are under the borders of the windows. they function fine but it's still a bit odd.

for ease of debugging:
OS: Windows 10
Computer resolution: 1920 x 1080
Spore Settings:
-Origin Spore + C&C + GA
-Windowed Mode
-1440 x 900 @ 60Hz
Let me know if there's any other info I can provide to help.
