Update 4:30 p.m. Thursday, to include response from the county registrar's office.
San Diego County missed sending seven ballots to military members by the April 21 deadline put forward by the Overseas Citizens Absentee Voting Act, according to California Watch.
Technical issues caused 13 ballots to miss the deadline, while more than 3,000 others went out on time, San Diego County Registrar of Voters Deborah Seiler said.
Of the 13 missing ballots, seven were intended for members of the military living on American bases.
The other late ballots were for people living in Mexico who have postal boxes in the United States, a county spokesperson added. The Registrar office sent overnight ballots to all 13 with an account number for them to return their voted ballots by overnight mail at County expense.
In total, 11 California counties missed the April 21 deadline, according to Califonia Watch.
