Possible bug when deleting a range of scenic elements channels with partitions

A bit complex so I may have easily made a mistake.

Cue 1 and cue list two where recorded with both dimmer and scenic element channels.

Then two partitions were created ( 1,2) 1: with dimmers 2: with scenic elements

Partition 1 add to Cue list 1 and partition 2 add to cue list 2

then in blind with cue list 2 you can type 

1 Thru 99 delete cue 1 thru 99 <enter> 

Does delete all the the dimmer channels created

Now when on cue list 1 to delete the scenic elements that were accidently recorded before partitions created 

100 Thru 199 delete cue 1 thru 99 <enter>

Says channel list empty 

but you cant do 

100 delete cue1

So it looks like you can't delete ranges of scenic elements when partitions are enabled.
