Hi Neil, 
Thanks for your feedback and appreciated offer ! ;-)
Last night I checked with my wife entry for entry and we had 2 more
different UUID's ...
... may be I was too tired !? ;-|
However today I only found the two WIN partition UUID entries missing
and something very specific with /dev/sda6: 

blkid shows UUID=E1C688 ... etc and another 
displays it as UUID=0E1C688 ... etc !?

May be one more mistake of myself ...
... or was it drag'n drop with "E1C688 ...etc !? ;-(

Below here are my blkid and fstab.
I grouped fstab to get a better overview and recognition of the
partitions plus its respective data.
I also started to fill the assumed respective data for /dev/sda6 & 7 !!

--------------------------------

TIA for your assistance to get back a clean /cleared and proper
constellation ! ;-D
If it helps or if needed I made a set of files from my UUIDcomp script.
Let me know if you need / want more info to check !?

HaHaHa ...
... I am using both arrays ! 
My emotional brain / as human starts the array with 1 !
My rational brain / as organizer starts the array with 0 !
