Multi-Row Variable datapills greyed out in Flow Designer

[Rosemary4]

My personal dev instance is on Rome. I'm trying to use the value from one of the columns of a multi-row variable set in a For Each loop to lookup the sys_ids in sys_user. The steps I've take are:

1) Get Catalog Variables from the Catalog Item in question

2) Add a For Each using the Array.Object from Step 1

3) Perform a Look Up Record

Bot the String for the column in the Array Object and the Item in the For Each loop are greyed out and unable to be selected.

Have I missed something obvious?

If anyone encounters this problem in future, the steps to resolve are:

1. Save your Flow
2. Type "cache.do" in the filter navigator and hit enter
3. Wait for the information screen to display
4. Refresh your Flow Designer tab
   
   The datapill in the "For Each" loop is now available for use
