Request type address not changed when changed name of request type

When i change name of request type (RT) its name in address not changed

Sample
Add RT "MegaRequest", address is ".../customer/sd-servicedesk-request-types-list/megarequest"
Rename to "MegaRequest2", address not changed
Add RT "MegaRequest", address is ".../customer/sd-servicedesk-request-types-list/megarequest2"
Rename to "SuperRequest", address not changed
Add RT "MegaRequest", address is ".../customer/sd-servicedesk-request-types-list/megarequest3"

In total, name - address:
MegaRequest2 - ..MegaRequest
SuperRequest - ..MegaRequest2
MegaRequest - ..MegaRequest3

Its all working (change, create request), but .... mmm... strange looks
