Batch update weight and parcel size details

[casiojuice]

For some reason unknown to me the weight and parcel size fields have been updated with duff information. This applies to hundreds of my listings.

Have looked to see if these fields can be batch updated but not found anything so far.

Does anyone know if these fields can be updated on mass?

Thanks

It appears the bulk edit changes the weight and size parameters.

Just bulk edited 13 items to replace some text in the item description and the process updated the weight and size which is an unwanted feature.

Anyone else out there having this issue?
