Akregator time for renew rss is break

[vista killer]

I have a strange problem with akregator. The timer to renew the rss is stuck to one minute. I try to change it but i put 10 min for example but after the 10 the 1 minute is still there and the renew works for 1 minutes. An example is like this

10 1 minutes

or

15 1 minutes

the 1 minutes is stuck there. Anyone else has the same problem?
