THINGS lump not found (even if it's clearly there)

I was trying to make my first PK3 from two WAD's and it went smoothly until the maps couldn't load due to this:

The THINGS are in the WAD's but SRB2 says they aren't. I looked for other threads like this but I couldn't find anything close to this situation. It happens everytime I try to load both of the maps.

Here are the files inside the PK3.

And the WAD's (the only difference between both maps are the map marker names)

Can you load the maps individually, as their own files? Additionally, are both of them in Binary or UDMF format?

Both in binary. And I probably said it wrong, I meant that the game crashes with this message when I try to enter MAP17 or MAP18. It doesn’t happen when I load both of the WAD files in their original states, so it probably something with how I modified the maps for the PK3.

(One of the WAD's in it's original state.)
I maybe deleted something critical for the stages to work, but as I said I never worked with PK3's before.
Also the PK3 stages have a new slot and don't replace any vanilia maps, but the original WAD's replace GFZ1 and GFZ2. (Idk if it's going to help you, but it still might be important.)

I suppose if you renamed the maps manually instead of saving them as different maps in UZB, that MIGHT have broken something? Though I tried that same thing with a UDMF map and it did not crash, so I'm not putting much stock in it.

You could try changing the level number in UZB, and exporting the maps and ONLY the maps, so you can drag and drop them directly instead of having to delete lumps inside them. That's the only thing I can think of, sorry.

That could actually work. I’m going to check it and then I will tell you if it worked.

YES IT WORKED THANK YOU SO MUCH! All I did was making two new maps (M17 and M18) and then copying the geometry from the original wads into the new ones and then inserting these WAD's into my PK3. You maybe were right about the renaming the maps, but I feel that it would make more sense if it was about me deleting the lumps than just changing the map name. Thank's for help again.
