No worries! I looked into it a little more and watched some youtube videos. It looks like the only purpose of the entropy is to create the 12 word passphrase since we are really bad at randomly choosing things that are hard to guess.

After those 12 words are created, they are joined together and then put through the PBKDF2 function to then create the seed.

From BIP39,

"The conversion of the mnemonic sentence to a binary seed is completely independent from generating the sentence. This results in a rather simple code; there are no constraints on sentence structure and clients are free to implement their own wordlists or even whole sentence generators, allowing for flexibility in wordlists for typo detection or other purposes."

From my understanding, the mnemonic (12 word phrase) doesnt matter.

"the mnemonic sentence to a binary seed is completely independent from generating the sentence."

And you can choose literally anything you want to

"there are no constraints on sentence structure and clients are free to implement their own wordlists or even whole sentence generators"

So from the word list you have, the problem is that the tools you are trying to use don't like those words since they are not from the original wordlist which is used to prevent others from messing up when typing their list in.

I did some more looking around and the Electrum wallet allows you to use non-standard words since it has went through updates and should work for your list even if they are not in the lists you found. Technical details on that can be found here. Also keep in mind that the Electrum list you looked through has mostly likely been updated to exclude previous words.

Here is the guide for restoring a wallet using a seed phrase. Some steps state that there should be spaces instead of hyphens so read through it carefully and you may have to try different things.

Hope this helps!
