V-Lookup only picking up some of the data

Hello,

Im having problems with V-Lookup, this has happened before...

It only brings back some of the data and not all. When doing my sensor check i see that the data is def there on the other page but the v-lookup has not found it?

Its only when I go in the cell,put my cursor at the end of the data and press return. then I revert back to the master page and it is there... But I cant do this for every cell as it will take forever..

I have tried copying the format, paste special values, etc but nothing seems to work... Any suggestions? Please help.

Thanks
Ant
