Boiler and radiator with slight leak causing pressure drop

I've removed the radiator in the kitchen for a new one, but I've not installed the new one yet as we're waiting it being plastered but because the rad has been removed it leaks very slowly, so every now and again the boiler drops below .4 bar, when I try and top the boiler up it doesn't let me top up, so then the boiler doesn't kick in, sometimes it just fires up on its own a hour later or if I reset the boiler or sometimes works, this has only started happening since we've the rad removed, any ideas. I've bled the rads etc.. Thanks
