Latest news show wrong url

In LatestNews+ When i choose a catagory with articles that are linked to from a menu item also, module show a wrong url adding a number somehow.
I havent been able to find out where the number 5 is from, its not the article, category, menu, module id.

Example
www.domain.com/my-site/my-articles
becomes
www.domain.com/my-site-5/my-articles

Any way to tell the module not to add that number in the link?

Thanks for the quick reply.

However the menu for the category is already made, its a part of the main menu.
www.rakebackbitcoin.com the module show in the right side if you want to see

Thanks for your help and great products

Not sure if i understand you correct here but ill try
original article rakebackbitcoin.com/en/all-about-bitcoins/how-does-it-work
becomes rakebackbitcoin.com/en/all-about-bitcoins-5/how-does-it-work when i click on link in module.

All articles that the module should show is in the same category and with menu link to them.

But im afraid its a joomla problem, after i been trying to solve this all night, it seems like joomla somehow create this link out of no where.

Another wierd thing is that, if i change articles titles to be linked in article option, then when i enter the article from the module with the wrong link, then if i cluck on the title again on the wrong url then i come to the right page.

I have just made the titles linkable again so you can see what i mean, try click article in the module, and then again when the article show try click title again.

This must be a joomla problem i think, just havnt seen this before.
