I'm installing some plugins and mapping some shortcuts on my init.vim file, the thing is that when I press the "tab" button on my keyboard in insert mode the program shows me this, in insert mode the tab doesn't work but in normal mode tab works correctly, I'm new using this text editor and I have no idea on how to solve this.
this is my init.vim script
