Entries for deleted devices

Hey, I have stor2rrd, lpar2rrd and xormon connected together, as part of testing Stor2rrd I added V5000 storage several times. Then I used this instruction: https://stor2rrd.com/how_to_remove_storage.php

to remove previously added devices. However, now if in Xormon I go to Storage> All Devices, I can see previously added devices on the side panel. In Stor2rrd, the entries for these devices are not visible anywhere or I haven't found them yet. Anyone could tell me how to get rid of them?
