Propeller type numbers on Mini 2

[Freddy K]

Hi everyone, new first time drone user.
After flying my Mini 2 today, I was checking the condition of the propellers and noticed that each motor had a different set of propellers.
I thought there were only 2 types of propellers (right-turning and left-turning), but my drone (3 weeks old) has pairs of type number "K1", "K2", "D4" and "B1".
Do these type numbers have any specific meaning or is this just a mix of older/newer propellers?

@Freddy K they are just the mould numbers ,that the props were made in and have no importance

Have a look at one of my previous posts. There are only two types of propellers and important you don't get them mixed up.
