Not displaying the stats in server about tiered HOT 2 OPEN

Its late i have to say, but i guess it doesn't hurt to write it here. We used that mod in our modpack and we saw stats after joining. But after leaving and joining again, there was no visible stats but they were still here. Long story short, when you closed game and opened it again and then joined, stats was back.

Same problem occurring here. When you join the server the first time it displays the correct name and shows the attributes in the tooltip. But then after disconnecting and joining again every single item which had an attribute has lost the name and shows none of the attributes in the tooltip. The attributes still apply but you just can't check what they are, meaning things like dull axe which reduces damage can't be seen after rejoining the server.
