Last name misspelled on stimulus check

Ok two of the checks came fine, but the third one had my last name mispelled on it. Have not filed 2020 taxes, and name was correct in the IRS database and on 2019 taxes. I found it odd that they could do a mistake like this since the information is correct in the computer. Has anyone else experienced this problem. Fwiw the bank helped me overcome this issue and informed me that this happened to several people.
