Why am I losing the ability to expand Quotes to the Quote Part level when I add Status = "Sent" to the view selection?

When adding a parameter to Lotus Notes view, I lose the ability to expand a quote to the quote part level.  This view used to work and has recently stopped working.  If I use this for View Selection:

SELECT (Form = "Entry1" | @IsResponseDoc & @IsNotMember( Form; "App5" : "Entry14" )) & (QTno < 30000 | QTno > 39999)

I can see a list of quotes with the fields I want and when I click a quote it expands in to the items quoted as well as the quote acknowledgment.

But when I make it:  SELECT (Form = "Entry1" | @IsResponseDoc & @IsNotMember( Form; "App5" : "Entry14" )) & (QTno < 30000 | QTno > 39999) & (Status = "Sent")

I get the right list of quote numbers but I can no longer expand the quotes to see quote line items.

We are currently running Lotus Notes 7, I inherited this system and am expected to maintain even though it is so out of date.    What I am wondering is why can a parameter limit the ability to expand a quote item?

Thank you for any help.
