Tag created by plugin can't be found by the plugin

Once you create a tag by typing, if you want to use it in the same note, the plugin can't find it and prompts to create a new tag again:

Maybe the plugin checks if the tag is already added to the note and if so, the prompt is to create a new one.
In that case, it would be better to show the tag in the drop-down list, and if it is already added then pass.
