Indentation is shifted when function completion is used

[tsunosekai]

I recently installed this nice plugin!

However, I have a small problem. When I type in a function, use completion, and press Enter, the indentation space seems to be shifted to the left!

The number of spaces that are shifted seems to depend on the number of function arguments entered. If the number of arguments is 1, there is no problem. If the number of arguments is 2 or more, 1 less space than the number of arguments is shifted. (If I change to tab indentation, this bug does not occur.)

The indentation settings in VS Code should be fine.

Could you please investigate?
