Hello @Dormilona ,
The best solution to this issue is to narrow down which contact(s) are causing the information to appear jumbled, then fix the information under the Contacts tab. If there are just a few contacts you can update each contact manually. If you have multiple contacts to update you can put them into a file and have a column for each field that needs to be update (for example, it they added extra characters or space after their First Name, have a First Name Column next to their email address, and any other fields that need updating). In this file add in the information without the extra characters or spaces. You can then choose to Add Contacts > From a file. After going through the steps to choose your file and label the data, on the screen to select a list you can check off that you are updating contacts, then hit import. This should correct the contacts information that was in your file.
