Lines on chart appear on chart of other currency pair

When I go through a list of currency pairs in MT4 (broker FXDD) inserting S/R lines, the lines appear on some of the other pairs. For example, when I inserted the lines as shown below on the NZDUSD chart:


They also appear in the USDCHF chart, in addition to the set of lines I drew for USDCHF, as below:


The lines on the NZDUSD chart and their duplicate lines on USDCHF have the same titles i.e. Horizontal Line 22367 and Horizontal Line 22328.

I have tried saving the lines as a template but the duplicates continued, so I tried uninstalling and reinstalling with same result.

Any assistance appreciated. A solution would be great.

Thanks.

Tough.
Maybe if you saved each currency pair as a different template?

Is that what people typically need to do? Would seem like a bizarre design decision.

I tried installing MT4 on another computer and the situation still continues.
