Data not fully updated with SQL server

I am using a report in Power BI. The problem is that, if I update data with the SQL server it gets updated 1 table of three of them. I mean, it appears that data is updated, but if I have new data in the other two tables it doesn´t update correctly. It gets frozen. Besides, if I connect again these two tables in Power BI with the SQL server I can see this new information.
So the problem is that two tables of three are frozen no matter what you update, and the only thing that I can do is connect again and delete the old one.
So ¿I can solve this problem without connecting again?
