I'm not sure what the problem is? But you can try disabling STP and  re-enable it. This isn't really advised! If you’re trying to change root  bridge or packet route change the switch priority or port cost instead.

It depends on the hardware you have but you can turn  off Spanning Tree Protocol (STP) on a per-VLAN basis, or globally on the  switch. Use the

no spanning-tree vlan vlan-id command in order to disable STP on a per virtual LAN (VLAN) basis.

no spanning-tree vlan all command in order to disable STP globally.

Or try

set spantree disable [vlans]
set spantree disable all


Becare in a production network!!

Note:

Extreme  care needs to be taken whenever you disable spanning tree because this  creates Layer 2 loops within the network. Do not disable spanning tree  in a VLAN, and make sure that there are no physical loops present in the  VLAN
