Problem with custom cards

[Lil Oldman]

First of all, I know this is not the place to say this, but I couldn't find where to submit feedback, anyways I've found a bug (I think) which it changes things at the moment of making custom cards, especifically when I decide to make it a sea serpent. The things it changes are the ATK (dont know if defense because I've only experienced this problem while making links), the link rating, it resets both the type and atribbute along with the link arrows. This problem only happened when it was a sea serpent, I've tried with other types and it seems to work fine with other types.
Sorry again for not knowing where I'm supposed to submit this.
