Both of them works in 1st Amico (A4KMichal) as expected, only. (They are recognized by Amiko and Amiko can boot from them.) Non of them are recognized by 2nd Amico (A4Ninka) by default. Reset is needed to boot from them.
I have got another input for you: When I removed SD card from 1st Amico, it wrote me this: https://drive.google.com/file/d/1H5J-E2xHgrv6G49rJGe3jAlhIOlgtQoL, what is ok, I assume.
So, there is something wrong in 2nd Amico .
