Who I have the same questioned this topic

My Google pixel 3 XL started receiving calls identified as voicemail 3 days ago. I have received multiple calls everyday since it started. Not sure if this is part of phone programming or not but, under call history I can see the latest call from my voicemail that happened this morning however, I can not see the ones from the days past. I can still see my prior outgoing and ingoing calls whether answered, missed, or declined from individuals and spam calls. Just not the voicemail calls.
