Update to Maplesoft Physics Updates v.779 or newer, then put Physics:-Latex:-UseTypesettingCurrentSettings := true at the top of your scripts, or in a worksheet before using Physics exports (e.g. Latex), or in your .mapleinit file read when you open Maple. Then your "current" Typesetting settings (whatever they are) will not be "extended", when you load Physics, or when you use Physics exports like Latex and execute a product that requires initializing the package.
In Maple, for a long time, the default was interface(typesetting = standard). Since some years it is interface(typesetting = extended). I like that. For a release or two interface(typesetting = extended) implied on Typesetting:-EnableTypesetRule(Typesetting:-SpecialFunctionRules); Typesetting:-Settings(':-typesetdot' = true); and Typesetting:-Settings(':-typesetprime' = true). And physicists enjoyed that, up to the feedback I receive,
But then those three Typesetting settings were removed from "interface(typesetting = extended)", which remained the default. After asking for opinions, we end up maintaining these three settings active when you initialize Physics (using 'with' or using its exports) and interface(typesetting = extended) (or the equivalent Physics command Setup(mathematicalnotation = true). Since then It's been several years, and it is the first time someone using Physics complains about using the prime or the dot settings - naturally because they are of no use in your case.
In brief, a possible solution to this is as implemented now: set your Typesetting settings as you prefer then enter Physics:-Latex:-UseTypesettingCurrentSettings := true, before using any Physics command or before loading the package, and your Typesetting settings will not be extended or changed.
As for any other issue you noticed (e.g. itsme seems to have crossed with other things but didn't provide examples), please recall the package is not finished, your feedback is very welcome, either describe them in an email with attached worksheet to firstname.lastname@example.org, or post that worksheet here (Green arrow please). Thanks.
