Double Word in BIP39 Seed Phrase - Is This Even Possible?

So, I was trying to generate a nice 12-word seed phrase. I used the standalone HTML file from https://iancoleman.io/bip39 and did it offline to ensure maximum security. After a few rounds of randomness, I ended up with a seed phrase that had the same word repeated twice - "mushroom."

I'm a bit concerned about the security implications of having a duplicate word in the seed phrase. Does this mean that the entropy is reduced, making the seed phrase less secure? Or is it just a rare occurrence that doesn't really impact the security?

I'd appreciate any insights or experiences from others in the community. Has anyone encountered this before, and if so, what did you do about it? Should I just discard this seed phrase and generate a new one?

Thanks in advance for your thoughts!
