Table misformatted - document attached




in my document this table is not correctly formatted in your latex.



Cell borders are not being hidden, that’s the problem right? or is there anything else?


You can see the different formatting

I think the problem is with the joined cells that there are in the table, because another table that I have with similar borders but simple squared organisation gets formatted well.


Another example where the first table is well formatted and the other two misformatted, but in another way compared to the latest example

Thanks. Bw.
