Tiny amounts of SC being transferred out of my Sia Wallet???

[edge10]

After a few weeks of leaving my wallet dormant, I opened it up last night and let it sync. This morning I looked at the transactions and there are 4 transactions for "0.088" SC coming out of my account.

Any idea what this may be? I tried looking up the transactions and don't understand

Should I be really concerned? Looks like some sort of automatic adjustment, but weird that a transaction was enacted without my knowledge.

Thanks,
