Sheet metal flange creates 0.01 mm relief gap

I often have a flat plate that I want to partially extend. To do this I want to use a flange feature with a 0 deg angle because it's a really quick and easy way to do this. However when I do this it creates a relief gap of 0.01 mm even though I have selected the "Tear" bend relief shape.
I know this isn't a practical issue because it's so small, but I find this very annoying. It doesn't give me the exact result I want when measuring or dimensioning. It also gives me issues when creating a pattern of these features, because I always start at the end of the plate so all of the extensions will only have the relief gap on one side. I know I could either use a face feature to add the extension or a cut feature to remove everything but the extension, but this is a lot more work.
I'm pretty sure that this hasn't always been this way, I have some files I created with Inventor 2024 and it didn't show this behavior. I am now using Inventor 2026.
Am I overlooking some setting I must have changed by accident or did the actual behavior of Inventor change? Is there a way to do this using a flange without having the relief gap (and without using something like delete face after the flange to clean it up)?
@johnsonshiue Could you look into this please?
