3815638 - Why is only one room type returning in Concur with discount modifiers matching the GDS, but when modifiers removed we see more room rates?

Can you advise why I am only seeing ONE room rate for a specific hotel, which shows the same one room in the GDS system using discount codes. Yet, when I remove the discount codes in the GDS and perform a new search, several regular rates return.

Client is wondering why they are only seeing one room rate with discount modifiers loaded in manage discounts, which matches the GDS search as well, but when removing the modifiers in the GDS they see more regular room rates , KBA , CON-MOB-TRV-HTL , Hotel , CON-CA , Cross Applications , Problem
