Import Drill Slots?

I have three slot holes on a given multilayer PCB. One of them should become an edge plate and takes from top layer to bottom layer. Another two slot holes should take from the top layer to the 3. layer like a blind via.
Altium can't generate blind slot holes directly. Therefore I split the excellon file that Altium generated into two files: ".TXT" (top to bottom) and ".TX1" (top to 3.). The TXT, which describes only one slot hole, appears incorrectly. I'm attaching both the TXT and TX1 files. I'm also attaching the original one, having ".all.txt" extension.
Have you got an idea, why the TXT appears incorrectly?
