Icon API in PPL generates Error 1026

[Thoric]

I've searched but found no answers. I added the Icon API (LabVIEW 2020 32-bit) to some code I keep in a PPL, just a simple Get VI Icon, Generate text, Set VI Icon. I receive error 1026 from Set VI Icon.vi, within Flatten Load & Unload.vi

It would appear this VI recognises it is part of a PPL and behaves differently, it calls a subVI that takes an absolute path and strips it back 7 steps, then adds paths. But this results in a non-existent path:

I can only assume it expects the PPL to be in a specific location, however it's bundled into my PPL in my location.

At this stage I'm thinking I need to take a copy of the Icon API and doctor it, create my own PPL and use that. But that feels dirty. And maybe I've overlooked something here? Advice welcome!
