Pianoplayerstar, could you scan at least a line of that score, including the beginning of the line, so that we see it in context. If it was actually written in the manner that you have put into your score, with the stems going the direction that you have put them and the rest, then somebody who didn't know what they were doing wrote it. This does happen, for example, when somebody writes out popular music for which we only have the audio form, and makes a mess because they don't know theory. But I suspect that this is not the case here.
In your latest score, the bass clef notes add up to 7 beats in 4/4 time, which is impossible, since it can hold a maximum of 4 beats.
Fwiw, if the circled F,C in the bass clef were played at the same time as the AC in the treble clef, both of them could be played with the LH, and all notes combined span only a 5th.
