The code for profile=1 is not very robust. It has been made to work specially for cube corners but other cases don't work so well. I'll try to improve it for cases like this.

Thank you.

I have found great use for this setting to keep smooth shading clean on larger faces while bevel modifier does its job on the edges.
Same result could be achieved with 2 stacked bevel modifiers, but this exludes working with the wight setting.

Unfortunately this doesnt work because Edge data for crease and bevel wight arent added to Bevels new created edges
{F145994} (applied modifier)

Is this an intended behaviour?
