Anyone else having trouble logging

Hi for several days now MFP seems to have trouble recognising things I scan. When I scan something it will come up with either something totally different or similar but with different nutritional information so still no good. And now today when I've put things in by hand it won't recognise the decimal point so for example 0.6 is showing as 6!! Have tried several things with less than 1 gram so decimal point at front and every time it come out 10 times more as my example. It's driving me nuts so any ideas please.
