pH changes when recipe copied

[NWGreengiant]

For the past few years I've used BF I have the problem with the copy function. When I copy a recipe it changes the estimated pH. With my recent Pale recipe the initial recipe was spot on with my acid additions to hit my estimated pH. I want to make a few malt changes so I copied the recipe. Simply copying the recipe changes the pH estimate to 5.51? This always happens and I'm getting annoyed with starting over from scratch just to make a few tweaks and keep the original. Any help would be appreciated, thanks

I imagine this is due to the water profile not copying over, as it's specific to each user. Any other ideas @Yooper?

In reality though, unless the recipe is building from RO, and you're also building from RO, copying a recipe will always need adjustment for water chemistry.
