Selection of curve does not reduce properly

Selection of curve from map shows small bug (clicking into indicated region). It appaears if

1. the same curve name is present in two tab_names, here Narva-Luga in qsr2, which appears in Estonia and in Russia. If I click into the marked curve region, also indicators from the Russian curve are shown. bug_2018_11_08.pdf
2. the selection of one curve was arlready reduced. Click into curve region will again highlight all indicators of respective curve. These indicators appear also in the SLI Time histogram, but not in the sea level curve.

It seems that the respective query only selects slis from curve = 'Narva Luga' directly from the database, and does not consider the already reduced subset (which appears in hirarchy).
