Unity 2018 problems

Hello, it seems that it has problems with unity 2018 ...
When a GameObject containing "Localize" component is selected to be edited in the inspector, an error is thrown through console several times ... this one

Copied style is null. Using StyleNotFound instead.
UnityEngine.GUIStyle:.ctor(GUIStyle)
I2.Loc.LocalizationEditor:OnGUI_Keys_Language_SpecializationsBar(TermData) (at Assets/[MelbitsWorldServerClient]/Plugins/I2/Localization/Scripts/Editor/Localization/LocalizationEditor_Terms_Description.cs:309)
I2.Loc.LocalizationEditor:OnGUI_Keys_Languages(String, Localize, Boolean) (at Assets/[MelbitsWorldServerClient]/Plugins/I2/Localization/Scripts/Editor/Localization/LocalizationEditor_Terms_Description.cs:227)
I2.Loc.LocalizeInspector:OnGUI_PrimaryTerm(Boolean) (at Assets/[MelbitsWorldServerClient]/Plugins/I2/Localization/Scripts/Editor/Inspectors/LocalizeInspector.cs:342)
I2.Loc.LocalizeInspector:OnGUI_Terms() (at Assets/[MelbitsWorldServerClient]/Plugins/I2/Localization/Scripts/Editor/Inspectors/LocalizeInspector.cs:249)
I2.Loc.LocalizeInspector:OnInspectorGUI() (at Assets/[MelbitsWorldServerClient]/Plugins/I2/Localization/Scripts/Editor/Inspectors/LocalizeInspector.cs:153)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

And some fonctionalities are not working properly ... for example, the one i needed, "specialization"

Is there any update or workarraund ?

Thank you

Perfect ... we just updated to v2.8.11 and it seems to be working correctly ... about creating several specializations at once, i'll keep that in mind ...

Thanks
