Hey welcome to the forum. I'm not saying that it's impossible, but especially 5 core and SLE seem to contradict one another to a large degree. As a withdrawn type, enneagram 5 is especially inclined towards inaction and substituting any action with thought by mechanism, even with sx in the picture. A 4 wing would only intensify this behavior as well as increase disconnection from the real and tangible reality. Se in socionics is characterized by force and action and even in the mbti is described by being catalytic in it's action style as well as impulsive.
A lot of people tend to conflate 5w4 with just being" highly intelligent, creative, and thoughtful," so that could potentially be the issue your running into, though it could also be a lot of other things too. 7 also has a line to 5, so perhaps you've reached a new level of health an unconsciously become more focused? It may be worth considering "neighbor types" like 3w4 (which has the 4 influence as well as is a type that often mistypes as both 5 and 7, especially when soc blind because the image focus comes across differently than typical descriptions) or enneagram 6 (which basically can appear like any of the types in the enneagram, but is specifically a halfway point between the mechanics of 5 and 7). It also could be worth considering LSI and/or ISTP, where that combination is a bit more feasible
