ESXi 6.5 - Guest Mem% doesnt match with Guest Resource Monitor memmory usage inside VMs

Question

I have strange issue with ESXi Host : in preview of VM, it shows not valid Memmory usage informations when compared to Resource monitor inside Guest OS, as example : VM name Assigned memory / ESXi Guest Mem % vs Guest Resource usage : VM1 4Gb / 8% vs 54% VM2 128GB / 6% vs 16% VM3 24GB / 12% vs 46% Is there a way how to show these real Guest OS memory informations in ESXi host? Having such bad information in ESXI has 0 value.....(Who knows if the other usage statistics are proper and valid then) (Data are read through vCenter 7, but have to say, that the values are same on host directly too) Thank you
