hmm, it is weird, I have never seen a linked button opening a blank form, you should either have an error message something like "No matching found" or no action happening, only the click itself.
I can suggest some tests:
- If you have another version, try on it
- Try to create a simple form on Screen Painter or B1Studio, put one field and one linked button to the StockTransfer (67) and see what happens.
- Double check if there is any add-on running or even linked button events handle in your code.
