PivotTable issue with duplicating field

Hello,

So a colleague of mine has set-up a pivot table for a consultation, with the entries of agree and disagree (and not answered). They've drawn this from imported data from a website we use for consultations.

They've added three additional responses, that fall under the "agree" category, however when they generated the pivot table, it's generating a separate row for "Agree". So say there are 15 agrees, 14 disagrees, 4 no responses and 3 agrees.

Is there a way to roll these 3 extraneous agrees into the larger set of agrees? I have a vague sense that it requires refreshing the "table" based on when I had a similar issue, but I can't remember exactly sorry.

Thank you.
