What you see here are probably the thousand separators for the displayed values. Integers, when displayed on screen, react to the localization settings of your app and use the appropriate thousand separators for the app's language/localization.
If you use a String data type instead of Integer, no thousand separator will be used. Or, of you have to use Integer because of database reasons, you could use the toString() function tot convert the value to a String before displaying it. Mind you, the value is still stored as an Integer, only displayed as a String.
