[Closed] controller with time range but no keys

this is an odd one. I have a script that truncates the timeline to the time range of existing keys.

but one object’s position script is mucking things up , and I can’t figure it out.

(getTimerange $ctrl_jaw.pos.controller #allKeys)
(interval 0f 37f)--has a time range!
$ctrl_jaw.pos.controller
Controller:Position_List
$ctrl_jaw.pos.controller.keys
#keys()
$ctrl_jaw.pos.controller[1]
SubAnim:Position_XYZ
$ctrl_jaw.pos.controller[1].keys
#keys()
$ctrl_jaw.pos.controller[2]
SubAnim:Position_Script
$ctrl_jaw.pos.controller[2].keys
#keys()--empty!??
