Yield Farm - Balance Error


is there a bug with the Yield Farm balance? I had yesterday a given figure on my Balance and today 5 SOVs have disappeared. So I had something like “190,945674” and today is “185,31132”.

UPDATE: Some hours later, my Balance is decreasing! I have almost 8 SOVs less

Many thanks!

Is this not due to rebalancing between rbtc?

The amount in the pool will fluctuate according to changes in price bteween SOV/RBTC

Now I know what it is. It is called “impermanent” loss. I found it thanks to Michael on the TG Group.
