Hi dear friends,
this is my example and I am trying to replace the missing value in "位置" which belongs to ID18


so I picked out the "Replace Missing Values(Series)" operator and set the parameters like:

Howerer, RM just kept telling me it couldn't get access to any data because of the wrong attribute type, whereas, I have already made sure that "位置" was regarded as a nominal attribute in RM, which was the exact type of attribute the operator can be applied to.
So here I am very confused about what's going wrong, does this have something to do with the data being in Chinese and not English?
Best regards,
sincerely,
Saefish
