First of all: Tails is not supported when using third-party USB installations. Proceed at your own risk
YUMI most likely configures an incorrect kernel cmdline in grub/syslinux/$BOOTLOADER. Make sure that it is (modulo language settings):
The specific problem you are reporting is cause by not having
nox11autologinthere, but omitting the others may cause other issues, potentially dangerous (w.r.t. security) ones.
