UID = Unique IDentifiers. This is similar to having a PC with a file list corruption at the file/folder level. Something caused this. A UID problem is a symptom not an end result. The cause can be a incorrect shutdown, corrupt memory,corrupt storage, Bad Chip, Bad Firmware.... There are multiple potential causes.
Hoben02 is offering the best solution. This problem will only get worse. If there was something similar to a ChkDsk utility for Android, I would suggest that. Your risk of not fixing will be increased Force Close, Apps that just break or not install, all the way to not booting up completely. Installing a new firmware is the closest that I know which can be offered.
