No, that's not it. The relationship tool is a representation of your database and its relationships. You made that representation conform to what I suggested (by removing the relationships there), but you didn't actually change your tables to actually fix the issues.
Plant_FK is still in multiple tables.
FinalProduct_ID is still in multiple tables.
Im sure there's others I missed that you just removed the line for the relationship but left the fields.
Also, your tables are still storing values in field names. For this let's use an example not related to your database:
tblSalesWrong
SalesID, SalesPerson, InsideSales2017, OutsideSales2017, InsideSales2018, OutsideSales2018
1, Dave, 10, 8, 12, 10
2, Sally, 4, 7, 7, 8
That table is storing 2 pieces of data in its field names that should go into tables--the type of sale (Inside/Outside) and the Year. The structure of the sales table should be like so:
tblSalesRight
SalesID, SalesPerson, SalesType, SalesYear, SalesQuantity
1, Dave, Inside, 2017, 10
2, Dave, Outside, 2017, 8
3, Dave, Inside, 2018, 12
4, Dave, Outside, 2018, 10
5, Salley, Inside, 2017, 4
...
Instead of 2 rows of 6 columns, the data is accomodated by 8 rows of 5 columns. Then when 2019 rolls around you simply add 2 more rows per salesperson instead of reconfiguring your table with more columns.
