Bridge curve not working properly

Hello,

I've encountered a strange problem with the bridge curve feature.

In the below picture you can see two splines (1 and 3) connected with a bridge curve (2). The item has been released in teamcenter so it's not modifiable.
As you can see there is no tangency between the curves, which is really strange.

I did the bridge curve with a radius constraint of 0.5mm, and if I double click the bridge curve feature on the released item it updates and becomes tangent.
How is this possible? How can I make sure that the curve stays tangent, as it should, when I release the item?

Finally, when I close the feature again the curve stays tangent, looking the way it should:

When a design program that we have analyze the curve it finds an inner radius of 0.069mm, which I think shouldn't happen when I limit the bridge curve
to 0.5mm.

Any ideas? How can this happen and how can I solve the problem?

Thanks in advance.
Regards
 
I also realize that I maybe have misunderstood how "radius constraint" works on bridge curve. I thought that the function forced a minimum radius on the curve. But when I look at it again it doesn't seem to be the case? Anyone that can explain and educate me? :)

When you first open the file, how are you determining that the bridge curve has lost tangency? Are you measuring angles, or is it a simple visual inspection? If visual only, try updating the display after zooming in on the bridge curve. What you see initially may only be the result of the graphics needing an update.
