The City Management Office in the City of Stockholm tells TV4 that Dadgostar's vote has been registered as usual.
Despite that, Dadgostar says she intends to vote on election day anyway, and she urges others who are at risk of being affected to do so as well.
"Take the safe route rather than the uncertain one anyway. It is so important that every vote counts so that there is no doubt about the election result afterwards," Nooshi Dadgostar tells TV4.
The Left Party leader previously said that she is "really upset" with the Election Authority.
"This looks really bad," she told Aftonbladet.
Early voting may have gone wrong in 52 municipalities, according to the Election Authority, which has published a list of the polling stations and times that may have been affected.
Among the municipalities on the list are Gävle, Helsingborg, Jönköping and the Left Party leader's home municipality of Stockholm.
"Now that I'm going through the long list of municipalities that could be affected by this, Rinkeby appears, where I was and voted with a large group of people. This risks undermining confidence in the entire electoral system," says Dadgostar.
On Friday, the Election Authority stated that approximately 500 voters may have had their early votes declared invalid. On Saturday, the authority adjusted the figure down to a maximum of 300 voters. The number of municipalities that may have been affected has increased from 50 to 52.
