air in the system...you will need to bleed the air out so there is only fluid in the system. Lots of info on brake bleeding on here and t'interweb...search is your friend

Dunno how you bled them but you could get yourself a vacuum bleeding kit (loads on E-bay for about £20ish ), really easy to use and you don't need anyone to help with the "up,down,up,down - hold" brake pedal thing which is a bit hit & miss

Did mine yesterday and was worried, car was stood for a few weeks with no front calipers on. They did feel a little spongy after I had filled and bled the system.
I thought I had got the air out but left it overnight and bled again this morning and the was a fair bit of air in the front calipers, maybe try leaving overnight too let the air bubbles collect and see if you can't get a bit more out?

When you bled them did the brake resevoir run dry as it needs to filled all the time to keep fluid in the lines, If it runs out you WILL get air in the lines, Or have you not tightened one of the nipples up, Does it still have the same amount of fluid in there or has any leaked out?

Don't know if I do it 100% but I always start bleeding the caliper FURTHEST from the master cylinder (passenger side rear) and then in seqeunce to the closest (drivers side front).
Fill fluid nice and slow so as not to introduce extra air into the liquid, don;t pump pedal like a nutter as this can aerate the fluid as well.
Good luck, sure you'll be fine!

..would that have anything to do with the pistons not working properly cos the brake fluid isnt getting in properly ???

Yes. If the pistons were seized the pedal would be rock hard. The fact it goes soft and can be pumped up is 100% coz of air in the system.
If the calipers have been put on the wrong side. (bleed nipple at the bottom). Its impossible to bleed all the air out.
Loads of people do it so dont be to bothered. Just swap the calipers over.

Years ago I did mine when fitting goodridge hoses. D'OH missed that there were two bleed nipples on each caliper. Had done the outside set of pistons but not the inner ones OOPS.

did exactly above and fitted my calipers wrong side
no amount of bleeding will fix, air rises and has to coem out the top
on plus side easy fix, swap over, bleed nipples at top, and bled in 20mins
its easy when you know how eh, lol
