Old call log issue

Yesterday I notice that the call log showed me very old calls (from May and June)
then I deleted all the call log.

Today suddenly show me 11 missed calls from 157 days ago (!)
How can it be I deleted all the call log and show me again the old calls - from May, June and then Jump to August, September ?
