Double Bass Hole in bridge

[Cmmcm12345]

i recently purchased a new to me bass, my first one with an adjustable bridge. I recently realised there is a hole in the treble leg, just below the wing. Is this normal? Is it
Cause for concern?

Looks like somebody drilled the adjuster hole a tad too deep. Shouldn't be a problem...
