Not respecting WorkAreaType from ExtendScript

I'm using Extendscript to send a portion of a sequence from Premiere to be encoded. Using the code below (straight from Adobe's sample code), AME has the correct In/Out points set, but the "Source Range" is set to "Work Area" instead of "Sequence In/Out".

var jobID_InToOut = app.encoder.encodeSequence(seq,
						outputFileNameInToOut,
						presetPath,
						app.encoder.ENCODE_IN_TO_OUT,
						removeUponCompletion,
						startQueueImmediately);

Premiere 22.5.0

AME 22.5
