Well, I can try. (As soon as I am back home.)
But what I don't understand: There should be "Leki" only once on the tent and no wooden part. The wood is for the tables. In MCX you can see the name three times on the tent. Just logically flipping the dds would not do the trick, I am guessing. It looks like he is doing also something with the sizing?
The source bitmap contains of three areas: One for the tent, just one time the word LEKI. One part for the wooden table surface and one green part for the legs.
As soon as it display correctly in MCX it should be ok for all of the three sims.
Ok, it is again a situation to quote a famous German footballer Loddar Matthäus:
"Again what learned." (He tried to say: Again, something learned)
I do not need to count on logic here I guess. The flipping of the dds file in deed, do the trick. What I don't understand: IF I would really liked to have the flipped textures displayed on the objects, How could I do it without getting strange results. Well... at least I would have expected a little different outcome if the flipping would be intentional.
However: It is working (in all three Sims) and a big thank you to the community.
Ah! It IS logical. It is because of the roof! The same parts getting textured with the LEKI because they are behind each other.
Now I can see, that the dds was displaying correctly but the wrong direction.
My world is back in shape.
