Tile issues

[wy477wh173]

GameMaker (IDE 2024.8.1.171, runtime 2024.8.1.218),
LDTK 1.5.3
LDtk Parser 1.4

My tilesets in GM and LDtk don't seem to match. Included are 3 screenshots. One from LDTK, one from GM Tilemap editor, and the last showing them in-game (single brush of the whole sheet stamped in the corner of the room). It seems to skip a few rows of tiles every so often as it goes down, though I'm not sure why nor can I find any setting or obvious trigger for the behavior.

Tested on multiple runtimes and IDE's and get the same issue back to IDE 2023.11.1.129 runtime 2023.11.1.160

I know this IDE/Runtime combo works with an older version of the importer(using it on an ongoing project and everything works great). I'm going to try using that older version (I think from 2022?) and see if I get different results.
