I forgot to position the glideslopes correctly when adding custom ILS to EFTU and EFMA, so the GS were pointing to the localisers at the end of the runways instead of to the GS antenna near the PAPI lights. This problem has now been solved for EFMA (version 1.5.4) and EFTU (1.6.2). The corrected glideslopes are the only changes in these versions!
