House preview and effect preview not same

[algerdes]

2021.15 - Single model of a matrix.
Added a waving flag gif to the sequencer.
Model preview shows as a vertical image.
House preview shows it as a horizontal image.

I have looked through everything I know, but don't understand why this is happening.

Any ideas?

send the layout screen shot of that matrix and the xlights_rgbeffects.xml. file

Cancel the alert.   I found it!

Turned out the layout was set to horizontal though the layout was actually vertical.
