first install issues after hard reset

[lneam]

last years, when i am making hard reset into my device, i am facing the same issues.
numbers 1 + 2 is two steps one after another

1.
after the download from playstore, i run for first time the app. I visit profiles > and press on the right the "gear" icon. Next, i press refresh icon but i get error message. Folder doesn't exist. I must run the android internal file manager to crerate the folder with name "4.2"

2.
next i exit the app with the android button "back". Then i run one file managet to visit the app main folder. This folder is created after the first run of app. I visit mapstyles folder and copy the suitable files. I run again the app. But when i visit > settings > mapsforge theme, there is only the app default style, not my data.
the only solution is to "kill" the app with the android Recent button. On the next run, my data is visible into mapsforge theme list
