Fighter Focused Weapon Shield issue

[Fuzzywessy]

So I'm building a sword and board fighter and at 5th level for my weapon training ability I took Weapon Training (Close) which includes light shields. At 9th level I took Weapon Focus: Shield, light and Focused Weapon (Close), but it won't let me select the light shield for some reason. Am I doing something wrong?

Here is a screenshot of how the focused weapon looks. When I click the dropdown it tells me "Nothing to Select"



Thanks again!
