Just created the Edit News page and when you insert a second Validation Show If, it wipes the first Validation Show If and jumps the code for that up into the head section! Check Line 43 of the attached.
This was happening with my Add News form too.
There is clearly a bug here which I hope you can sort for future releases. For now, as this is a time sensitive project, I'll need to manually repair it which removes the usefulness (point) of the extension entirely. So frustrating. :(
