Balls stuck in left channel. Switches need to be bent back?

The plunger feels “sticky”. Doesn’t have that smooth feel when pulling back. It can still plunge the ball up to the top of playfield, but will need to be properly examined.

One LED flasher bulb is dead. I swapped it with another bulb to ensure the problem was the bulb and nothing else. The current bad bulb is in the upper playfield right side. This socket had also fallen out of its holder. The clips do not hold tightly.
