B Button Dash Patch Glitch

When I dash either down or right, the character dashes but the sprite is not running, they're just standing still, it works fine when I dash either up or left, it's only right or down.
This issue only happens when I have the sprint shoes equipped and I'm pressing B to dash as well.

Any tips on how to fix this?

Here's the patch I'm talking about :
