Bug with 'ip' command where build a stuck list of interfaces

Hello.
With 'ip tunnel add tun0 mode ipip dev enp1s0' make two interfaces
called 'tunl0' and 'tun0'.
Late with 'ip tunnel del tun0' remove only 'tun0' and forget the
'tunl0' in the list.
with this you can not do anything else in the list, it can not be
created and it can not be deleted. It is hanging.

# ip link list
