ICX7250 , port security: mac address is refreshed on interface and not moved...

Hi, since last december I have this security warning on our ICX 7250 switches where port security is enabled, its happening randomly on some ports.

It's not a "violation", but a "refreshed" ?!?

Example of today:
W:Security: Port Security secure MAC address xxxx.xxxx.9c91 is refreshed on interface ethernet 2/1/28 and not moved to interface ethernet 2/1/25 in vlan xxx
W:Security: Port Security secure MAC address xxxx.xxxx.9c91 is refreshed on interface ethernet 2/1/34 and not moved to interface ethernet 2/1/28 in vlan xxx
W:Security: Port Security secure MAC address xxxx.xxxx.9c91 is refreshed on interface ethernet 2/1/34 and not moved to interface ethernet 2/1/19 in vlan xxx

While a violation look like:
W:Security: Port Security violation at interface  ethernet 2/1/34, address xxxx.xxxx.4374, vlan xxx

My guest is the latest version of Windows 10 doing something and talking to other workstation on the same vlan, but not sure what?

Does someone seen these warnings on there switches?

thank you
Eric.
