IfIndex not updated in ipinterface table on change

We monitor a Cisco router with mulitple interfaces. After a while the ifindex on some interfaces changed. The new indices of the interfaces are correctly set in the snmpinterface table of OpenNMS after a provisiond rescan. But the ipinterface table was not updated. Here I see the old indices. The only way to get the new indices here, is to delete the specific ip interfaces from the device and start a rescan.
