Below is the message displayed by electrum when importing a BIP39 seed phrase. That explains why electrum developers don't like BIP39 seed phrase and they use a different algorithm.

Yeah. Bing's AI showed that they were trying to future proof its seed generation. Apparently, it'll always know how to read a seed. Maybe trying to fix a problem that doesn't exist or perhaps genius. Multibit used to use something similar with their own approach. The great thing is that there is a market of ideas.
While my momentary need makes this annoying, I trust the software and controls. Just wish I could see the BIP39 seed.

I appreciate the help. Maybe I'll dig more into seed generation.
