I bought a commercial house in Wuxi, but now I find that the developer has made a mistake in filing, and the house has become a shop. I haven't applied for a property certificate yet. Will it affect me? Do you want to cancel it?

yes, the service life of shops and houses is different. This is a serious problem. Negotiate with the developers and ask them to cancel it and then file a new record. I don't know the time. After they hand in the information, they have to be audited by the staff of the Housing Authority. The length of time is entirely up to the Housing Authority. If there are enough people, the less they handle, the faster they will be. This does not require the owner to pay.
