Buy / Sell tool should not dispapear

When i do a buy or a sell with the buy/sell tool. then when i go to the chart to darg one of the lines (SL/TP) it disapears, would like have the option that it would not disapear, so that i can see when dragging the lines The RR value increasing or decreasing. now i have to drag, let the mouse go, see if i have reached my desired RR and then continue dragging if the desired level is not reached.

this happens in Dark mode, not sure if this is the case in light mode.
