why are descriptions in tape not carried forward to next year

Unfortunately we only have the tapes carried forward if they are done on fields that have values that will be carried forward into the new module.

By example, this field in the screenshot will CF. Make sure to tick the box Carry forward in the Tape window

This occurred despite having ticked off carry forward description as indicated? 

it depends which box you are trying to carry forward, as mentioned above, only boxes that are normally carry forward, will allow to CF the tapes
