Bug: Dropdown Selection Don't Recognize '1' unless changed and changed back.

[DivertedCircle]

Describe the bug
The Skill Proficienny and Skill Expertise dropdown menus for quantity cause a UI bug in the character builder if the option is left as the default '1'. To correctly set it to a choice of 1 you must change the number from 1 to any other number, then back to 1.

To Reproduce

Steps to reproduce the behavior:

1. Go to the subclass builder.
2. Select any number of skill proficiencies using the checkbox. Do not change the quantity to choose.
3. Save and go to the Proficiencies tab in the Character Builder.
4. Click multiple skill procifiencies. All will be highlighted though you should be limited to 1.

Expected behavior
Only 1 choice should be allowed.
