Screen Reader Reads out Previous tags on copied/pasted pages
I often copy content from other screen and courses when using some similar interaction/functionality. I have to be careful to change all labels and alt-tags. However, I just noticed that alt-tags from the original version still seem to be read out at times by screen readers. I've attached 2 images. The first one is the screen as it starts which has five buttons going to five different layers. Everything on this page is read out correctly according to the Alt-Tags. The second shot is of the second layer. Everything is read out correctly until you tab back to the first button. The screen reader then reads out the original tag. This happens on subsequent layers too on all the previously visited buttons. If you navigate through without going back there are no problems. I can't for the life of me find out where the system is getting the original ALT-Tag from.
I have also included an image of the tab order showing the tagging on each button.
