Multi-tag extraction doing something funny for "S" column

[sarahlukens]

I got another one for you Thurston - I have it working on my personal computer. It's with the multi-word tag extraction. I don't know if that screenshot pasted, but I took a two-gram ("pm route") and tagged it as "S", which nestor made pm_route. However, when I extracted the CSV, pm_route didn't make it to the S column. But I have similar examples where the same workflow made the underscore 2 grams go to the I and the P columns

Here is another related issue - why is "REPLACE" not getting extracted in these example rows (but is on the rows around it)?
