Execute the snmpcollector apply_templates callback via the snmpcollector probe utility. (Ctrl-P)
Wait a while to see if that fixes the issue, If not, then try to force component rediscovery for the device. If that does not work, deactivate the main Template, save the change. Verify that the template is removed from the interface for the device, then Activate the template.
If that doesn't resolve the issue, double-check the template that is applied to the devices. See if it has the correct box checked for the desired outcome, e.g., enable or disable Publish Alarms. If so, correct the setting, then apply the template and check the result.
