press "Apply" button after you have finished configuring the trunks

STP (Spanning Tree Protocol)
Spanning tree is a link management protocol that provides path
redundancy while preventing undesirable loops in the network. For Layer
2 Ethernet network to function properly, only one active path must exist
between two stations. The spanning-tree algorithm calculates the best
loop-free path throughout a switched network. STP forces redundant
data paths into a standby (blocked) state. If a network segment in the
spanning tree fails and a redundant path exists, the spanning-tree
algorithm recalculates the spanning tree topology and activates the
standby path.
