Search for standards using standard code

Hi there!
Last year, I was able to search for standards using just the standard code (RL.2.1 for example). This year, when I typed in codes, the standard would not come up. This makes it take much longer to add standards to lesson plans because you have to either scroll through ALL the standards or search for each individual standard using key words. I would like to be able to search for standards based on the standard code again!
