I cancelled a transfer and now it won't let me offer the player out

I accepted the loan transfer but didn't read the terms properly as thought the transfer was going through at the end of the loan. So when it came to him leaving, I noticed it wasn't what I wanted so cancelled the transfer. Now it wont let me offer the player for transfer any longer? 

I've tried demoting and promoting him to the u23s etc

Any one experienced this before?
