您好，请问亚马逊品牌备案被不是标准字符标记拒绝是什么原因呢？

原因是：
Trademark drawing type is not STANDARD CHARACTER MARK or TYPESET WORD(S)/LETTER(S)/NUMBER(S) (US only)
The drawing type of your Trademark is not STANDARD CHARACTER MARK or TYPESET WORD(S)/LETTER(S)/NUMBER(S). Currently, Amazon Brand Registry can only accept these two types of mark drawing types.
