'Find/Change' fails for 'Change All'

'Change All' fails where I use ' End of Paragraph' [^p] and 'Change Format'. Change/Find is fine but need to process a considerable amount of text.

e.g.

I am asking to change:

ABC £1,000 ^t £1000

to

ABC £1,000 ^p £1000

whilst changing format to new paragraph style, so it ends up like this:

ABC £1,000

£1000
