Custom decorations clipping through floor in game and builder

[soss]

I got some decorations from Realm667 and they clip through the floor in game and in the builder. How can I fix this? I use Ultimate Doom Builder and render my game with OpenGL and my sourceport is GZDoom. I originally took a screenshot in UDB but they all came up with an error message. The error message is down below

change sprite offsets in slade.

the two values determine the position, the line going side to side behind the sprite determines the floor (value 0)

Select the sprite in he slade editor and move up with arrows.

Was gonna say, it's probably your offsets..
