TAG system - not userfriendly

I have tested many templates from GavikPRO and have also a lifetime membership. I love to test.
In a new project I work with, we have chosen "music" for many reasons.
BUT when we came to items and should fill in some useful K2 tags, we was shocked.
The interface is not as expected and it is useless.

Here it what I see:

What I normally have seen and like much better is:

Please help me with this problem. What I want is of cause the normal one which I can just type in the words and then press "Enter".
The system in MUSIC is just a list which is even not in alphabetic order.

Hi

I think you are making some confusion there.
We don't have any responsibility on K2 tags system because K2 component is not ours.
We only provide theme support. That's it

If you have any problem regarding this issue, i recommend that you ask support on K2 official website.

Cheers

I am really sorry for my question. I have never thought of that the template which support K2 does not have anything with K2.

When I went into the "Parameters" for K2 I found this:



I learned that the tag system has two options. I had never seen this and this is what confused me.
Thank you again for your helping attitude.
