Toolset Forms offers Conditional Groups which can feature each several conditions. If you happen to have more than one such Conditional Group on the same form, and any but the first Conditional Group features more than one condition, then the first Conditional Group will be enlarged by one additional, empty condition on the Post Title when you save the form.
The best workaround is to make the first Conditional Group and make it a “dummy” one. This means leaving its content empty.
