Help with tv programme

  Please can someone assure me I'm not going mad. A few weeks ago there were adverts for Alan titchmarsh love your home and garden. I have even seen the first one which was helping a mum and dad who were both in wheelchairs. They knocked down an outside wall i watched it. I suddenly realised I havent seen any others. On its catch up hub it says 15th Jan. Nothing since. Where has it gone. Tuesday its. Help

   Thanks I've just recorded it but it does say series 5 ep 3. But where has the main programme gone. It was on mainstream channel 3 on a Tuesday. There's only been 1 episode then nothing. Weird
