Saving an advanced filter with an "Or" in it sometimes reorders the "Or" to the last element

[bdnettleton]

Describe the bug After creating or updating a filter with an "Or (mark an or between blocks)" sometimes the order of the blocks gets changed moving the "Or ..." to the bottom of the blocks. When this happens the filter does not work correctly.

The first attached image is of a filter being edited immediately before saving, and the second attached image is immediately after saving.

Repeated deletes and saves eventually seem to fix the problem.

After Save:

Expected behavior Saving a set of blocks shouldn't reorder the blocks.
