Security Detail View shows security no longer in portfolio.
This has been a problem for some twenty years! Back in the 1990's I sold 100% of a security. I checked "hide". However, even though it is "hidden" and has a zero balance it will occasionally show up in the "Security Detail View" drop down list of securities. It can go months without it showing in the list and then suddenly it starts showing up again! I know with all the problems in the world this is not high on the list but it is still annoying. There should not be some hidden tiny fractional shares somewhere since I bought 100 shares and after a two-for-one split I sold 200. Nice round numbers so I don't believe that is the problem. The only thing I can think of is some strangely corrupted file. However the security does not always show up. I would appreciate any thoughts on the matter.
