I think the "errant" dot is in the right place (in line with the one above). The issue I see is that the e above it is too far to the right. I'd move that back and then adjust the tie with \shape to miss the dot on the c (also to miss the b at the other end).
To hide the flags, try "\once \hide Flag" before the note. But sometimes I write e4*1/2 to write a crotchet (i.e.no flag) but with the timing of a quaver.

Two items for which I request search terms to locate solution/commands. The first is the errant dot on the c4. This has been presented/discussed/resolved in a previous thread. Please provide a search term to locate that thread. The second is a search term for the command to eliminate two flags, one on the e8 the other on the e16. I am using version 2.22, Thank you for your kind attention. Mark Stephen Mrotek
