The bottom left white button and the yellow band of the first picture are the same thing I think. My guess is the yellow band is the abbreviation of the white button. So that’s why you don’t see any okurigana (hiragana suffixes after the kanji) for the yellow band.
資財積降 = 資財積み降ろし　=　しざいつみおろし　= Unloading (and possibly loading) something (materials, assets, cargo?, not clear what you’re unloading).
積む（つむ） = to load
The other two buttons are “OK”(I think…not sure why they wouldn’t just use the romaji for OK there) and “Cancel”.
Keep in mind that I’m not an native speaker so please double check with one if you have the opportunity to do so.
