Camera Help...

[Nano]

So I have had my camera working quite well for a while, its a nikon P500. Taking some decent pics, but tonight for some reason I am trying to take some actinic shots, and I have the macro setting on, like always when shooting close, and I click the button, and its takes like 3-4 seconds to take the picture, and they are coming out blurry as if a "time lapse" kind of a shot. i dont get it, I haven't changed any of the settings, but its not working... ughhh

anyone know what I may be doing wrong?

Like I said it had been working fine until now.. not sure what the problem is.. I can't seem to change the shutter speed anymore, I can't find the setting..
