Messed up manastones

Something happened to these standard type manastones from Small GM Gift-boxes after updating 3.7 to 4.0

Look below for example.


This is the Manastone: MP +105 from Small GM Gift-boxes during 3.7 back then

Now this is the Manastone: MP +105(?) from Small GM Gift-boxes today at 4.0

Both of them has the same name of the item and the Grade level. But the descriptions looks a little different, the new manastone says it will only increases 100 MP opposed to the item name, and it can't be merged together either in inventory or storage like acting as a "new and separate" item. They are few more standard type manastone acting like this coming from the today's Small GM Gift-boxes.

Hoping for AMs/GMs look into this minor problem. Thanks for reading.
