An oddity with the replacements via 'locl'

I noticed a fact that baffled me.
I do not know if it is physiological, or derives from some mistake of mine.
Imposed a 'locl' substitution lookup that concerns both lowercase letters and small caps (the example I report is purely simplifying; I did an experiment by modifying EB Garamond as a test).

Now:
1) the lowercase letter (in my experiment the <a>) respects the replacement of the lookup;
2) the same substitution is also applied to the <a> small cap, I don't understand why;
3) the substitutions for the letters small caps are not carried out at all.
What's strange or wrong?

    Do you see anything wrong? 'locl" is lookup04, 'smcp' is lookup 20; both applied to all languages

    I understand, although in reality it is my fault that I have probably complicated things.
    I have a font in which, immediately after the 'aalt' (0 and 1) lookups, I have two 'locl' replacement lookups.
    https://www.dropbox.com/s/q7r6jcf5e9iyhwc/test-Regular.otf?dl=0
    Now, in lookup 3 the substitution cedilla.sc -> ccommaaccent.sc for MOL and ROM works.
    Instead in lookup 2 the i.sc -> i.dotsc for TRK does not go and I always find the lower case <i>.
    Apparently the settings are the same, and I can't understand this different behavior ...
  • Ahhhh solved. It was lacking
    i.dot --> i.dotsc

    in "smtp" lookup.

    Sorry for posting a not useful tread and thank you
