In Zotero note, the numbered list can't be indent correctly

Ao Yulong

When I indent the numbered list by using tab key, I can't get the expected one. What I get is:

1. Level one
[tab]1. Level two
[tab]2. Level two
2. Level one

But I want:

1. Level one
[tab]1.1 Level two
[tab]1.2 Level two
2. Level one

And I cannot change "1. Level two" to "1.1 Level two" manually
