Post From: Chart does not refresh simulated position / order fills after changing T&CQ Symbol

Hello,

I believe I have found an issue related to changing Trade and Current Quote Symbol and Use As Trade Only Symbol on an existing chart.

I can reproduce two related problems.

Scenario 1 – Simulated position is not displayed

I have an MNQ chart:
Symbol: MNQU26_FUT_CME
I set:
Trade and Current Quote Symbol: NQU26_FUT_CME
Use As Trade Only Symbol: Yes
I open a new simulated NQ position.
The working NQ orders are displayed on the MNQ chart, but the simulated NQ position/position line is not displayed.
Trade > Show Orders and Position is enabled.
Trade > Only Orders From Chart is disabled.
Reload/Recalculate and restarting Sierra Chart do not solve the problem.

However, if I duplicate this chart, the newly created duplicate immediately displays the simulated NQ position correctly without changing any other settings.

Scenario 2 – Historical order fills disappear after switching back

On the same chart I remove the Trade and Current Quote Symbol:
Trade and Current Quote Symbol: blank
Use As Trade Only Symbol: No
The chart is therefore again a normal MNQU26_FUT_CME chart.
Historical MNQ order fills which should be displayed disappear from this chart.
Show Order Fills is enabled.
The fills exist in Trade Activity Log for exactly the same symbol and Trade Account.
Load Order Fills for Current Day Only = No, and sufficient historical days are configured.
Reload/Recalculate and restarting Sierra Chart do not restore the fills.

Again, if I duplicate a working MNQ chart and change only its bar period to match the affected chart, all historical fills are immediately displayed correctly.

Therefore this does not appear to be related to the symbol, Trade Account, bar period, or missing Trade Activity data.

It appears that changing Trade and Current Quote Symbol / Use As Trade Only Symbol on an existing chart does not fully refresh or reinitialize the chart's trading state.

Creating a duplicate of the chart appears to force this initialization and immediately fixes both the position-display and historical-fill-display issues.

I can provide screenshots or a Chartbook if needed or record a short video to show ideally
