Is This A Faulty Binding? Stain Seeped Into Cracks

[BorfBorkBorf]

Hello!

So post-staining, I've found that the stain has seeped into fractures within the binding. Is this because of an incorrect/damaging installation of the binding?
The photos show the worst offenders, but this is pretty much around the whole binding.

Should I contact Pit Bull about this?
Any advice would be appreciated.

Thank you in advance!
Julian.
