Software Update Notifications

Does anyone know if you can delete/remove some of the software update notifications? the usual updates are fine they go when done but I have two I cannot get rid off, they appear every time I start, even if accepted previously. First one is red calendar one I think, and the second is reminding me I don't have an active data package..... not a big issue but a pain as they mask real software updates until i realise there are three update notifications...
