Strange behavior of the plugin or agent

I have GLPI 9.2.1 with FusionInventory plugin 9.2+1.0 and FusionInventory-Agent_v2.3.21-1.

I can not count something about tour PCs.
One my PC in GLPI change the name and other information about youself.

In PC Historical I can see
61569    2017-12-27 16:57    Plugin_FusionInventory (37)    UUID    Change 6C0B315E-867A-5642-9AE3-F02AF106B2F0 to 55ADE930-5FDF-5EC4-8429-15640684C489
61568    2017-12-27 16:57    Plugin_FusionInventory (37)    Name    Change Vasiliy’s iMac to user’s iMac
61562    2017-12-27 16:52    Plugin_FusionInventory (37)    Operating system    Add a link with an item: MacOSX (3)
61559    2017-12-27 16:52    Plugin_FusionInventory (37)        Add the item

then later
62649    2017-12-27 17:22    Plugin_FusionInventory (37)    UUID    Change 55ADE930-5FDF-5EC4-8429-15640684C489 to 369D18AE-A9AC-546C-BFC7-C75B26DF29F8
62648    2017-12-27 17:22    Plugin_FusionInventory (37)    Name    Change user’s iMac to iMac — Maxim Kolesnikov

and so on

In agent Historical
62647    2017-12-27 17:22    Plugin_FusionInventory (37)    Name    Change users-iMac-2.local-2017-12-25-12-30-39 to iMac-Maxim-Kolesnikov.local-2017-12-25-12-14-44

61567    2017-12-27 16:57    Plugin_FusionInventory (37)    Name    Change Vasiliys-iMac.local-2017-12-25-12-19-29 to users-iMac-2.local-2017-12-25-12-30-39
61566    2017-12-27 16:57    Plugin_FusionInventory (37)    Device_id    Update of the field

61558    2017-12-27 16:52    Plugin_FusionInventory (37)    Version    Update of the field
61557    2017-12-27 16:52    Plugin_FusionInventory (37)        Add the item

So, I have one PC in GLPI but Information about him is changing by information about several real PCs.
