Observation Field not showing up in Report Selection

I created several observation fields specif to my project, all start with teh letter DSF: see Observation Fields · iNaturalist

One of the fields " Observation field: DSF Plant Association (2nd)" has some entries in it, yet when I run my data extract the field does not show up?!

Any help much appreciated. p.s. all the other fields do show up.


to confirm, you have personally added that observation field to at least one observation?

oh? me personally? no. I guess you have just provided me the answer. I will give it go. thank you
