ARM_MBO is a stock I have already taken trades on.

Today, its price isn't displayed normally on the right side scale of charts: for example instead of the normal $129.56, it says 129 - 59/-71.
I am unable to enter trades because of it.

So I go to Global settings -> Symbol Settings. Note that I am using custom symbols.

At first, I see "Price Display format" is written in that weird 129 -59/-71 formatting.
I manually edit it to something normal: 0.01. Sierra Chart says the default setting here would be 0.001, which isn't correct. The default should be 1 penny always. But anyway, I enforce my manual 0.01.

I reconnect.

After that, I see nothing particularly wrong with the custom settings for this stock anymore. The problem keeps happening. The same thing started happening with NKE_MBO today as well, a stock that has always been displaying its price normally. This randomly happens on some days, on random stocks. I have no way of predicting this. I always update the symbol settings of course, but this is not enough. Here are two screenshots of the settings for ARM_MBO and NKE_MBO. Note: when I took these screenshots, NKE was displaying its price properly again thanks to my manual modifications. ARM was not, despite having exactly the same settings.

I figured after half an hour of tinkering, that I had to use the default "Price Display Format" of 0.001 on ARM_MBO so it works again. Now its price is showing as 129.620 on charts. I can deal with it, but I'm sure it'll be grounds for this problem to repeat itself some day.

I can deal with it after my trading sessions, but the fact that it can happen for no apparent reason out of the blue is weird.

We need to see an image of your chart when it is showing the wrong prices. Please follow these instructions to get us the image:
Support Board Posting Information: Attaching or Posting a Screenshot/Image (Optional)

Also, we want to see what happens if you are not using the custom settings that you setup for this symbol. To do this, you will need to duplicate the symbol to another and give it some name that you know will not get confused with anything. This way, you have a "backup" of the settings you had created. Then remove the ARM_MBO symbol from the symbol list.

Then open a new chart for ARM_MBO and let us know if you have any issues with that chart.
