Help find the correct Helvetica Neue font

I need to match the Helvetica Neue fonts listed in InDesign's "MIssing Fonts" dialog (viewed when opening the document). I already have older Type 1 version of all the weights, but I would like to purchase the OT fonts to match the font names exactly so that this dialog box does not appear.

Here's what one document is asking for:
"Helvetica Neue LT Pro 75 Bold"
also "...65 Medium" and "...45 Light"

Here's what another document is asking for:
"Helvetica Neue LT LT 45 Light"
(Yes, the 'LT' is duplicated)

I am not able to locate Helvetica Neue in the Adobe Store with "Pro" in the name. Does anybody have an idea what is up with the 'Lt Lt'? Maybe these aren't even Adobe's fonts (Linotype appears to call their own "Neue Helvetica")?

Any suggestions appreciated, thanks.
