This record cannot normally be saved with blank values, but due to changes to other records can have internal business rules or other scripts cause these values to be cleared. Resolution<!-- /*NS Branding Styles*/ --> .ns-kb-css-body-editor-container { p { font-size: 12pt; font-family: Lato; color: #000000; } span { font-size: 12pt; font-family: Lato; color: #000000; } h2 { font-size: 24pt; font-family: Lato; color: black; } h3 { font-size: 18pt; font-family: Lato; color: black; } h4 { font-size: 14pt; font-family: Lato; color: black; } a { font-size: 12pt; font-family: Lato; color: #00718F; } a:hover { font-size: 12pt; color: #024F69; } a:target { font-size: 12pt; color: #032D42; } a:visited { font-size: 12pt; color: #00718f; } ul { font-size: 12pt; font-family: Lato; } li { font-size: 12pt; font-family: Lato; } img { display: block; max-width: ; width: auto; height: auto; } } To thus fix the issue, the appropriate Target Color Schemes [pa_target_color_schemes] record (/pa_target_color_schemes.do?/sys_id=5947e121d7021100ef2281537e61034f) should be exported from an out-of-box instance and imported into the customer's instance overwriting the invalid Target Color Schemes record as found on the instance. If such an out-of-box version of the record cannot be located, the values can be set manually as follows, and then the Target scheme record saved: Range color 1: Critical Red Range color 2: Critical Red Range color 3: Warning Orange Range color 4: Positive Dark Green Range color 5: Positive Dark Green Selecting the appropriate color from the selector will then auto-fill the related "Display" and "Color" fields.
