My finder tags won't work

Question

Hello, i run osx 10.9.3 on my macbook retina and have been using the finder tags happily for the past few months. recently though they started not working. when i tag a file under red for example, i see the file itself getting colored red, but it won't show up in the red folder. and when i try to untag a red file in the red folder , it won't do it. it's very frustreating.
also i never used the colors other than red, but i just checked the other color tags and there are a bunch of random files tagged under different colors in those folders and i did not do them.
so, anyone have an idea?

Let's start with your wireless router. I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Power-up the modem; wait at least 10-15 minutes.
Power-up the base station; wait at least 5-10 minutes.
Power-up your computer(s).
In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.
