Global Beta 6.7.26 install fail via TWRP

I'm on global beta 6.7.21 and got an update notification of 6.7.26. A 93MB file. It downloaded ok but whenever I try to install it via TWRP it shows failure. Shows that the fingerprint doesn't match. i thought since I patched the boot.img with UBP it showed problem. So I went on to flash 6.7.21 first, then without patching boot.img tried to flash the 93MB ota. It failed again and showed the same failure that fingerprint doesn't match. It should be Xiaomi/kenzo/************* whereas it is Xiaomi/omni_kenzo/************* . Anyone on global beta miui8 having the same problem? Shout out any possible solution I may have missed.

The flashaholic in me can't live with 6.7.21 when there's 6.7.26 is out.
