Pattr, Preset, and Bindto

I've been working on something that uses a single interface (a collection of GUI objects) with a tab to switch between multiple identical versions.

I've been using pvar so far, but this means everything has to stay on the same patcher level, and I know pattr is a lot more powerful.

^{Concerned about how heavy using a whole bunch of unseen GUI objects would be I had also tried using a single set of GUI objects and a set of colls to edit and store their settings, but this got complicated beyond my grasp.}

In the example I've made, this mostly works: you can use the tab to switch binding between objects, you can store and recall presets, but when recalling presets sometimes it copies the state of one GUI object to all of the others, destroying the preset. I can't figure out what's going wrong.

It's not a permanent change, because if you just switch back and forward between presets a few times you can recall the original settings, but it's a glitch that makes this unusable.

Thank you so much to anyone who can offer advice!
