Map importing incorrectly

[HudsonCW]

When importing multiple files into one map, the map image is cropped and the walls are offset. The two maps are 60x50 and were exported at 150 grid PPI. Part of the second map was cropped out as see in the image below vs what it looks like in Dungeondraft.

Second attempt with smaller maps at 50 ppi grids; 3 maps: two 16x11 and one 35x20. This time the second and third order map were way smaller than the original.

I should mention I am on Foundry 0.8.8, DnD5e 1.3.6, UBI v2.1.0, no other modules enabled.

Could you share the files so I can have a deeper look at it?

I assume it is as reported a few times, that the images are not loaded correctly and therefore the stitching process does not work as expected. Besides the workarounds already implemented I have currently no idea why this happens and how to prevent it.

How large are the maps? The larger the maps are the higher the possibility it will happen.

The first image was two 60x50s with a file size of 54.6 mb, I thought size might be an issue so I scaled it down to 50 ppi at for a sum of 17.4 mb. The second comment was three maps at 50 ppi and the sizes I mentioned above with sum file size 4.94 mb. I will attached all of the files used to this comment. Desolate Park and Desolate Park D1 are the maps used to make the first comment, Adorned Cellar Secret, Adorned Cellar, and Cursed City hideout. I forgot to mention this in an earlier comment as well incase it could be related but the maps were made using Dungeondraft v1.0.1.3

Same thing is happening for me.
