M9 (himauhl) GPT table

Hello

I want to split userdata partition of my M9 into two parts. What is the right tool for it?
I tried android-gptfdisk but it shows that GPT partition table is very strange.

After I run gdisk from the package above I can see the following message.

It looks like GPT partition table and/or MBR are specific. Nevertheless my M9 works well I can boot it and use it.

Could somebody give me a hint about working with M9 GPT partition table?
