Help with welding issue

Hi
Wondering if anyone can help. I can’t seen to weld the parts that are circle red.
The welding functions are blacked out so I can’t click on it. I have tried ungrouping it and trying to weld just the 2 but it won’t allow me to.
Help
Running the latest version on Lightburn

You don’t have any items selected in your screenshot. You must have 2 items selected to use the weld function. If that is not the issue, upload the file so we can see what the issue may be.

It happens only on the new version when I highlight 2 things to weld. I downloaded the older version 1.6.03 and there are no issues with the welding.

The probability that the shapes are not closed is high. Send the file and we will see.

Sometimes the Cut Shapes tool is your friend. Try it on the circled shapes.

You may have to Break Apart shapes first.
