As user "gwszvh" said, you can see that topic. The problem can called: module appears again.
The Ot News is designed for homepage, so if:
1. you put the module at homepage,
2. choose module to display at homepage only (in menu assignment section when edit module in back-end)
If you meet 2 above conditions, then when click to readmore or link, it shows article on the page which module won't appear again. (See demos here
If you put module on inner page, the module will still show when you click to readmore or link.
My topic has a few answers with no solution yet for me. Maybe it will work for you.
Its called "OT News - miss the action from read more"
Actually we have "The solution for all that cases" - that is "add custom Itemid to the readmore link and article link, then choose module not shown on that Itemid/page". This solution required you know some about Joomla, php so can modify the module.
There is a topic same this problem and solved, another module, but can help you all understand why.
Thanks for using our products!
