I've actually checked this during the last hour, and I was unable to find any solution me neither...
But it sounds like it's occured by sth in the Construct2 export system, not directly by the plugin itself - I tried to only create a select item with three options, without any others properties, without tick nor updateposition, etc..., and the bug still occurs.
Hopefully it may help you, just please let me know if you find a solution, I would appreciate to know what occured this.
