Hi,
I am not sure why the articles are showing up twice and will need to check the admin panel for the same. Kindly check the admin access details you have provided and let me know the correct details.
I could not find the read more link anywhere but since you are seeing a language variable instead of text Read More, the language variable does not seem to be defined in language file.
Same is the reason you are seeing the contact form labels like that. I have created a language override file in your site root / languages/ overrides and have put the variable for text These fields are required, in it. Now you can see the text appearing in the contact form instead of variable. Similarly you need to add all the variables you are seeing in the form with whatever label text you want to show instead of them.
