I have a problem with the blog template plugin

I have a problem with the blog template plugin. https://premium.wpmudev.org/project/new-blog-template

I have created a test website to explain my problem:
I have this website that I create as a temple http://din.ilogic.co.il/ ,this website has a Manu restaurant manager plugin ,I use this plugin https://wordpress.org/plugins/easy-restaurant-menu-manager/
My problem is when create duplicate template like here: http://din2.ilogic.co.il/ everything that I writ in Hebrew is showing as ???? ( only from what is coming from the tables of this plugin?

If I try active restaurant manager plugin on any other web website than tables on database are created fine it works great
Can you please tell me why the duplicate tables for this plugin are paste as question marks ?
