alarms that won't go away in opmanager central

i've setup a remote site (probe) for testing. and i have about 5 alarms that are no longer alerting, all green in the central and all green on the probe side. also, any new alarms that i generate (for example, i've made a device unavailable) clears up just fine when i make the problem go away (making the device available again for this example). so everything looks fine, except these 5 alarms that got "stuck" there. i have no delete option on the alarms section (is that supposed to be like this?)
