Items not support in 1.8.2

[stevenfoo]

I encounter that the below is not supported anymore. The below is a normal trigger checks. Anyone have ideas?

{ZABBIX Server:vfs.file.cksum[/vmlinuz].diff(0)}>0
{ZABBIX Server:vfs.file.cksum[/etc/inetd.conf].diff(0)}>0

{Template_Windows:system[procrunning].last(0)}>10

Also the below triggers have status Enabled = green color.
However at the expression part it is shown as red color.

{Template_Windowsroc.num[].last(0)}>300
{Template_Windows:agent.version.diff(0)}>0
{Template_Windows:system.uname.diff(0)}>0
{Template_Windows:status.last(0)}=2

And ideas? Other item in trigger template for Template_Windows have
status Enabled = green color and expression = green color.
