I have a "test" SD card with 3 versions of iGO 8.3.5 and 2 versions of IGO Primo 2.4, running on an old MioMoov 360 with VisualGPS. All 5 versions are running just fine with the latest HERE 2018/Q2 maps, while running exactly the same copies with TomTom maps 2018.06 (10xx fix) or 2017.12 displays Austrian city Graz as "Stajersky Hradec", and capital Wien (Vienna) as "Viden" (or something like that - I guess Czech or Slovak names for them). My language set is always Slovenian (not Slovak). I'm pretty sure I didn't have this issue with older TomTom maps (2017.06 and older). Slovenian names would be "Gradec" and "Dunaj", by the way.

Does anyone have a clue what might be a reason for that (somehow Slovenian and Slovak to be erranously mixed or so?)? I don't have anywhere some Czech or Slovak language set (all settings for HERE and TomTom are exactly the same, and no issue with HERE!).

And, even more important - how to fix it.I don't mind if the names are displayed in original language (Graz / Wien) or in Slovenian (Gradec / Dunaj), but the language as now (Czech / Slovak / Polish...?) s quite confusing for me (not for those two cities that much, as I know what they are by their location on the map, but there might be some more such names for places located in the areas I'm not that familiar with...).
