Problems with copy and paste - sudden arabic formatting

[FlyingSaucy]

I'm having a problem when I copy and paste between documents. 

Both have their languages set to English UK but when I copy from one to another the text reformats itself into 'arabic'. That is it reads from right to left and is right aligned. The actual font and text remains as it was.

If it was just a case of ranging left again that wouldn't be a problem, but all quaestion marks etc have been relocated as well and simply selecting all the text and applying 'english UK' doesn't fix the problem.

Does any one know how i can fix the issue and prevent it from happening again?

Thanks -

It can to be something with similar named paragraph styles, e.g. the default paragraph, or an object style carrying over which can hold paragraph settings and styles too.

I think I've solved the problem… 

It seemed to be an issue with the Adobe World-Ready Composer paragraph setting changing it to Adobe Single Line put everything back to how it should have been. Not even sure how that composer came to be used in the first place.
