I was having similar issues. I am using connect 3.13.251
I am using pulldata. The pulldata works fine on windows version of the field app and in connect however in ios (iphone) it works for 2 fields but not for 2 others. The only difference i can see is that the 2 that dont work have decimal places?? depth and maxcasing work fine however top and bottom return the words "top" and "bottom" rather than the number.
I tried copying the csv values and pasting as values over themselves but still would only pull 2 of 4 values.
I resaved the csv from "pipetable" to "pipetable1" and now it works. (I did this half way through writing this but post)
No need for any solutions but this may help anyone with same problem - similar to a turn it off and turn it on again solution.
