Hi @evrimfeyyaz, thanks for submitting this issue! I'm able to reproduce the issue you're describing. StrictMode invokes several functions twice to detect side-effects, and it seems like that may be what's happening here. I'll take a closer look.

Also note that the behavior you describe will only happen in development mode.

This was also happening in v4.x and should be fixed in v4.2.0. Coming soon to 5.x branch.
