Only listing one instance of an investment

I have the same holdings in two accounts, but my portfolio only lists one of them, leading to an inaccurate total. Example: I own “fixed income fund A” for 8500 SEK in account A, and “fixed income fund A” again for 8500 SEK in account B. But only account A shows up. The total should be 17000 SEK of the fund, but only 8500 SEK is counted. It should recognize duplicate holdings and combine them into one total in my opinion.
