Incorrect numerical order of products please help!! (product names are numbers)

[llonk]

Hi, I have a problem with the management of products in the frontend, the alphabetical ordering only considers the first character.
In my case, the products are named a number (eg 20, 45, 300, ...), the alphabetical order should be from low to high (20, 45, 300) which is what I need, but the frontend appears collapsed, (20, 300, 45) because it only uses the first character.
How I can fix it?
Thanks, I did not know what to do.
