Removing abyss socket suffix does not revert sockets to original number

What platform are you running Path of Building on?

Windows

What is the behaviour in-game?

Once abyssal socket suffix is removed from an item, the socket itself is removed from an item and its maximum number of sockets became default (4/6)

What is the behaviour in Path of Building?

Once Delve modifier (Has 1 Abyssal Socket (suffix)) is removed from an item (under modifiers section), links on the item remain as, for example, R-R-R A, which later triggers a warning if one places 4 gems into the given item.

How to reproduce the issue

1. Create a new item which can have abyssal socket (armor piece)
2. Click 'Add Modifier', select 'Delve' and Has 1 Abyssal Socket (suffix) mod
3. Click 'Add'
4. Once added, click 'Remove' against added modifier

Expected:
Sockets revert to original (i.e. R-R-R-R)

Actual:
Abyssal socket is still applied (so it is still R-R-R A)

使用列出的 modifier 步骤和链接的 Titan Greaves build 重现该问题，然后跟踪移除 Delve modifier 后物品的 socket 如何更新。完成的标准是移除 abyssal socket，并且物品在不触发警告的情况下恢复到原始的 socket 数量和连接。
