Lightroom plug-in sends TIF instead of ARW

Hi folks – recently purchased the big 3 and Photo AI.

I’m overall fairly pleased with this amazing software, but am running into an issue: when using Lightroom, I’ll select the “Edit in Topaz” option and it sends the image as a TIF despite the image being an ARW.

Is this an issue with the plug-in? Am I better off just putting the ARW in Topaz as my first step, then getting to work in Lightroom?
