about the Manufacturer Minimum Age

@CR_Amazon hello,i have two questions about this col.Could you help me resolve this issue?

1.My product’s manufacturer has recommended the age as 8 years and above. However, I have promoted the product with a recommended age of 15 years and above, as I believe this product is quite complex and not suitable for younger children. Would this approach help avoid the product being classified as a children’s product?

2.When adding a new product using the web interface, the Chinese translation of "Manufacturer Minimum Age" is "制造商最短寿命." This translation is unclear in Chinese, as it does not mean "Manufacturer Recommended Minimum Age." Instead, it seems more like the product's shelf life.So I made a mistake while filling out the information. How can I correct it?
