I am working on a window schedule for a project. I have a room that has the same window in multiple locations, when I choose to merge those items the unit size width and height disappear, even on the units that don't have multiples.
Thank you very much for the question! From the description and screenshots, it looks similar to defect DEF-5947. In AC25, there is an option for changing Merge behavior. Please find the attached screenshot to see how to find it. If you open the Merge option dialog and click OK, the field will be visible. Could you please give it a try? Best regards, Minh
