In my GO source code, updating the import section, brackets remove one byte when hint is selected

This plugin is really great! I like it!

When I 'm writing the go import section, brackets suggest me several choices. If I choose one (from mouse) one byte is removed. This is annoying...

Ex: If I type os/ it shows at least os/exec and other choices, but when I choose, os/exec, it writes os/xec instead of os/exec

Is it a known issue?

I will investigate this, unfortunately I have not so much spare time and can't mantain this plugin properly.
