TWRP thinks that I use a different phone

Hi I'm a noob to Root, Recovery, flash and everything but I'm technical noob.
I just want to install CM12.1 Nightly to my Xperia Z2 (Bought it on ebay)

The official rom with Lollipop was installed.
First step, Bootloader unlock, no problem, official unlock code from Sony, use Flashtool, done.
But second step, get root access was more difficult.
I tried a few tutorials but the problem was lollipop, as far as I understand.

Than I found this tutorial:
(Google: "How-to-root-Sony-Xperia-Z2-and-Z3-on-Android-5.0.2-Lollipop")
I'm not allowed to post urls.

With some small issues everything seem to be fine.
Check with RootVerify App, root granted.
Restart TWRP starts, great!

Install choose CM 12.1 zip.
Error: "This package is for device ... sirius (I know that's my phone!); this device is leo." WHAT? NO! It's not!

Can someone help me (Noob)??

Kind regards

Phone thinks I'm in Japan?

Actually I'm in Idaho but my phone sporadically thinks I'm in Nakahira, Japan. It happens numerous times a day. I'll pick up my phone and the time and location are set for Japan. I'll open Google maps and it's also in Japan. My GPS is always on and my phone is stock unrooted. Anybody else experience anything like this or have an explanation?
