Can't update icon for Things

I don’t see any icons at all. How did you find version 2.17

I have 2.18 loaded on a LG v930 tablet, android ver. 6.0 and a Samsung phone SM-A600A, android 9. Icons are visible on the tablet and only 4 in Lighting; 20 in Office on the phone. All other categories are blank. There a place holders but no icons. If I change them on the tablet, they show up on the phone.
