In the settings for build teams, there is a very long list of all the unique synergies in the game. But when new ones are added, they show the slider in the middle, but have a value of zero. If you want to use them, you have to adjust the slider so the value updates from zero. If you're using a new browser, you have to do this for the entire list of unique synergies.

Expected: When adding new synergies to the settings for building teams, the slider should be in the middle (currently correct), and the value should default to 50 (currently not correct).
