[Koha] Single Branch - "NO LIBRARY SET" - Auto setting Library

[Spurgeon]

Hi,

Greetings!

We have a small library and want to operate koha in single branch mode.

We are using Koha 3.12

In the intra page, the default library is NOT SET and we need to set it
manually every time we login to the only library we have.

Am I missing some setting or
Is koha capable of detecting and setting the only library as default?

Request your kind help on this...

Thank you.
Sincere, warm regards
Spurgeon
