I’ll reply to the first image since I was your controller in FMEE.
I remember perfectly that in Antananarivo center you asked for a Radar Vectors (RV) service 300 NM from the airport, that both the FAA and the IFATC manual for controllers agree that it is a purely VFR service, knowing that you had a established flight plan, that is, you could fly with IFR rules and you could have requested another approach that would have been more “realistic” such as ILS/GPS.
In “Roland Garros Approach”, the approach frequency, you asked for Radar Vectors again, to which I responded by giving you some new vectors, that is, your flight plan from that moment was not valid anymore, you had to follow my instructions, as the manual says in section 6.11.11
I left you in a recognizable position for tower, in this case, entering straight in to the airport and then you were already fully established with that pattern leg (Final), I handed you off to tower, to which tower responded with a new pattern entry and a sequence and the subsequent clearance, this in order to find your position on approach to the airport.
(As I also noticed in Trend, there is no need to spam the “Request frequency change” command, the controller is fully capable of hand you off to a new frequency, excessive use of this command can result in reports)
I don’t really see anything “out of the ordinary” in the second image, from what I see, it’s also a Radar Vectors service, so the same principle applies, approach leaves you in a recognizable position (in this case Right base) and then approach handed you off the tower, to which the tower must subsequently give you a new pattern entry, a sequence (if applicable) and a clearance, again, so that you can find your position on approach to the airport
