Apparently, the OMS home has been applied PSU 13.2.0.0.171017, which already included the fix of the bug. Customer performs following steps to reproduce his issue,

In Monitoring Templates window, click the name of desired template and get into template details window, then click the Glasses icon in 'Edit' column besides metric 'Generic Alert Log Error'. In the new windows, the 'Alert Log Filter Expression' can be changed, but the new value cannot be saved (retained) after click OK. The value goes back to old value when come into this window again. It seems a bug/defect here. Actually, the window is a view-mode (read only) window with title 'View Advanced Settings: Generic Alert Log Error'. Yes, it gives you opportunity to type words in view-mode window, but does not change anything, a funny behaviour.

It is not a correct way to edit a metric in a monitoring template by clicking the template name. Instead, select the record (row) of the template and click 'Edit' button. In 'Edit Monitoring Template' window, the metric can be changed permanently.
