Visitor log is showing more separate entries for the same 1 one visit

Hi, using old Matomo 3.6. The visitor log sometimes shows several separate entries for the one/same visit/visitor. Attached is a screenshot and red circled. The visitor has the same IP address, same time of visit, same device and same “coming from”(Google in this case)…again its an old version of Matomo so maybe it can’t handle newer visitor settings/devices etc.

Thanks,
Richard
