Thanks Jennifer, I don't believe there are cases where values are hidden inside of other values, although I'll definitely keep an eye out for that - thanks for flagging it.
I did just find a workaround, but still a bit perplexed what is causing it and it will be tricky to apply on a larger scale. To get the "values" I was defining, I originally used R code to create a dataframe of unique strings, exported that as a csv, then copied the values from a csv into the Category selector. When that didn't work, I also I tried copying the values from a text file to be safe/ensure no hidden spaces were present. That didn't work either, leading to my original post.
I just tried going into the configuration settings of one of the indicator elements I wanted to filter, clicked the upward arrows to the right of "Data table," then copied the value from that table and pasting into the Category selector, and it worked. I am currently using a dummy dataset with only 6 unique values so it wasn't a big deal to scroll through the table to find them, but the full datasets will have hundreds of values (which was already going to be time-consuming pasting from a text file). Could this possibly be some type of bug, or is the way I was doing it from R --> csv file --> text file not the best workflow?
Thanks very much for any help you can provide!
