No save button for music on hold page

I am using FreePBX 2.10.1.2
I cannot find anywhere the save button on the music on hold page. I want to turn it down a bit as I have received a few comments that it is too loud, but when I set the volume to 75%, there is no way to save it.
Am I missing something?

Read the roll over help menus. That volume is used when importing a MoH file to adjust the volume. Once it is imported there is no way to change the volume of the file. You need to delete it and reimport the file and pick a lower import volume level.
