So after to switching to HUSH after finding out that morning Innova seemed to be broken I have fixed up my wallet and started to mine again

All seems to be going well on lychee however I noticed this come up in the miner console.

It looks like Lychee is sometimes mining Vivo as you can see in the screenshot I have posted the blockchain height and the difficulty match Vivos....

Please explaine
