I dont believe anyone has reported this issue. I have a modded server me and a few friends created and every single time we load in we will have multiple smithing templets in our inventory without fail. Same thing happens in singleplayer. When I disable the mod we dont have this occur.

Which smithing templates? Are they vanilla items?

They appear to be vanilla. Showing hidden tooltips doesnt bring up any modnames. Suspicious, Danger, Shell, Plated, Drip, Verdant, Pride, Margin, and Heart Armor Trims always spawn in. Same for all of the members of our server.

I didn't have this issue until my latest release of the new update to our modpack. I added I believe 27 mods/dependencies and then this issue started happening and stopped when I removed Quark.

Those trims are definitely not vanilla. The vanilla ones (including latest version) are: Sentry, Dune, Coast, Wild, Tide, Snout, Rib, Wayfinder, Shaper, Raiser, Host, Flow, Bolt, Ward, Eye, Vex, Spire, Silence.
The only thing I could find on the trims in question is a russian site for some server.
Try and figure out what mod (or datapack) they are coming from. The only mention of armor trims in the source code of Quark has to do with the color runes.

ahhh I see can you possibly give me that link?

wait I see it now its the Trims Expanded Mod! Could've sworn I disabled that lmao thank you for the help
