Alias can no longer be set for merged plots

Server Implementation

Paper

Server Version

1.18.2

Describe the bug

on merged plots you can not set alias for a long time.
no teleport or placeholder, but reassign does not work, because says there is already one with the name.

alias so to speak exists but you can not use it and it is not displayed.
it also looks in the SQL like not all merged plots get the alias.

To Reproduce

• Set alias -> successful according to chat
• Placeholders don't show alias, you also can't teleport to alias.
• Set alias again, with the same name -> even says would be taken.
• go through all single plots of the merge, to delete the alias ... of 6 plots that are merged. have it mostly only 2-3 the not displayed alias which can then be deleted.
• after that you can start again above with alias set and happens the same again.

Expected behaviour

set alias and the plot again reachable to teleport and placeholder.....

Checklist

• I have included a Plot debugpaste.
• I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

No source file or test is named; start by reviewing the linked Plot Debugpaste and reproducing alias assignment on merged plots in PlotSquared 6.6.2. Trace alias state through reassignment, teleport and placeholder lookup, then verify that merged-plot aliases are consistently stored and usable without stale SQL records.
