Blue vertical Line in AIS

I think only  when the same bank/company entry  is appearing in both SFT and TDS/TCS  it is clubbing them together with the Blue line in the "Derived" column but showing the individual figures.. As screenshot is png file, unable to upload.

In my case,  2 SFT entry for Bank FD and RD interest  are there and one TDS entry for the same bank for interest paid/credited for the same bank. All 3 entries in Derived column is accompanied by the Vertical Blue line.
