Batch item preview pic

[Josh Rayburn]

Create batch list of cabinets that have slab doors (let's say they're MDF and the material is a beige color)
click 'check all'
go to 'adjust features'
change doors
select a slab door with a different sheet stock, same banding (let's say the new color of the new material is green)
note the preview has changed for all cabinets, they now have green doors
save job

re-open job
doors show in the preview pics as beige

is this a bug?
