My Sims4´s saved matches are mixed with other Origin account.

Good afternoon I´m maresmedrano63.
The other day my daughter used my computer to open an account Origin, and she bought the initial game of SIMS4 and two expansions more. She was playing and when she finished, closed her account. Then I opened my Origin account and I opened my Sims4 and to my surprise all my saved matches had been deleted. In addition, my game has been turn in English (just as she changed the language in her account because she likes to play in English). When I load game the family she created in her acount appears.
In the end what I did was to download a family that I had created and I had uploaded online to share previously and I was playing with them but today when I opened my account to play with my Sims4 again has disappeared my saved matches! :S I don't know why the accounts have been mixed if we have our own different Origin accounts. I don't know why this happened. I have turn my account Origin and my Sims4 game in Spanish but it is still in English. Please if anyone knows what's going on, let me know!
