Since we only have words to communicate with correct usage is critical - a time capsule is a hardware device designed for use by Time Machine for backups - but since it is basically a hard drive it can be used for other uses - are you running Time Machine to bcakup to your Time Capsule?
If so starting TM will not cause any change in your system - what exactly are you seeing and what else changed
How are you "checking all back ups"? The only way to see a TM backup is to restore it using the Time Machne software
