Have you tried changing the emblem on Battlelog in some of the older Battlefield games like Battlefield 4? Usually any issue that happens on the companion app can be avoided on Battlelog.
I have changed the emblem in BF4 using a different EA account, but that was about 5 years ago, so I'm not entirely sure.
I heard that there's a limit to the number of parts you can use to create emblems if you don't have BF1 Premium, so is it because my purchases aren't reflected in the companion app?
No, it does not make a difference premium or not for the layer/parts limit.
Excuse me, but to summarize my environment, I'm using the Steam version of BF1 Premium, with Chrome as my browser. When I copy and paste a code into the console via the Companion app, I get an error. I have no idea what's causing it.
