Hi Merc!
Hope all is well. Just to chime in, what Skandiluz stated is correct regarding the Platform at its core being the same (The EdgeProX is just a White Label of MotiveWave software) and works the same. But they just have their own little tweak to it.
If I’m not mistaken the reason why you probably seeing that version of splash screen is because you’re maybe using EdgeProX License from EdgeClear? Instead of directly from MotiveWave itself.
I had this experience when I first started using MotiveWave platform. I originally was using the subscription from EdgeClear (EdgeProX) even though the actual platform download file was from MotiveWave website directly. But I later ended up Purchasing the Professional Edition from MotiveWave directly since this version is not offered by EdgeClear. And after updating the license in the system, the splash (EdgeProX) screen went away and replaced it with the Original splash screen from MotiveWave!
